    alpha-decay chains of Z=114, A=289 and Z=118, A=293 in the relativistic mean-field model

    Full text link
    A comparison of calculated and experimental Q_alpha values of superheavy even-even nuclei and a few selected odd-N nuclei is presented in the framework of the relativistic mean-field model with the parameterization NL-Z2. Blocking effects are found to be important for a proper description of Q_alpha of odd mass nuclei. The model gives a good overall description of the available experimental data. The mass and charge assignment of the recently measured decay chains from Dubna and Berkeley is in agreement with the predictions of the model. The analysis of the new data does not allow a final conclusion about the location of the expected island of spherical doubly-magic superheavy nuclei.Comment: 4 pages REVTeX, 4 eps figures, accepted for publication in Phys.

    Eight experiments were carried out involving 24 roosters, three feedstuffs, six replicates, being in each experimental unit, a rooster. Prior to each experiment the birds were starved for 36 hours to empty their digestive tract. At the beginning of each assay the roosters were individually weighed and then force fed the exact amount of 30 grams of feedingstuff. Force feeding was performed by inserting a tube in to the crop via the oesophagus. After feeding, the birds were returned to their cages. A tray was placed under each cage to collect excreta. At the same time six roosters were kept fasting to take account of metabolic fecal energy and endogenous urinary energy. Exactly 48 h after force feeding, the voided excreta was collected quantitatively and processed in laboratory. The apparent metabolizable energy (AME), N-corrected metabolizable energy (MEn), true metabolizable energy (TME), and N-corrected true metabolizable energy (TMEn) values of the feedingstuffs, in Kcal/g, expressed on air dry basis, were, respectively: algaroba meal, 1.26, 1.46, 1.74 and 1.73; defated rice bran meat, 1.21, 1.37, 2.22 and 2.22; full-fat rice bran meal 2.51; 2.70, 3.09 and 2.79, incubatory waste meal 1.29, 1.37, 1.63 and 1.47; dendê meal 1.40, 1.69, 2.08 and 1.91; guar seed 0.94, 1.29, 1.37 and 1.33; integral cassava meal 2.82, 3.01, 3.34 and 3.27; cassava meal 1.40, 1.76, 2.64 and 2,65; corn gluten meal 3.53, 3.62, 4.33 and 3.95; ground corn 3.04, 3.24, 3.65 and 3.50; fish meal 2.65, 2.22, 2.57 and 2.50; soybean meal 2.08, 2.17, 2.65 and 2.51; high-tannin sorghum grain 2.47, 2.75, 3.04 and 3.02; low-tannin sorghum grain 2.90, 3.10, 3.47 and 3.38 and wheat meal 1.26, 1.50, 2.06 and 1.88. Because of the correction of the metabolic and endogenous losses, the TME and TMEc values were higher than AME and AMEn values.Foram desenvolvidos oito ensaios biológicos, com um total de 24 galos, testando-se, em cada um, três alimentos, com seis repetições, sendo cada galo uma unidade experimental; mais seis galos foram mantidos em jejum. No início dos experimentos, os galos foram alojados em gaiolas individuais e mantidos em jejum por um período de 36 horas, para esvaziar seus tratos digestivos. Em seguida, foram pesados e forçados a consumir uma quantidade de 30 g de alimento, introduzido dentro do papo através de um funil colocado no esôfago. Após a alimentação, os galos retornaram para as gaiolas providas de bandejas para coleta de fezes. Paralelamente, seis galos permaneceram em jejum, para se determinar as perdas endógenas e metabólicas. Durante as 48 horas após a alimentação forçada, as fezes foram coletadas com intervalo de 24 horas. Os valores médios de energia metabolizável aparente (EMA), energia metabolizável aparente corrigida (EMAn), energia metabolizável verdadeira (EMV) e energia metabolizável verdadeira corrigida (EMVn) dos alimentos expressos em Kcal/g de matéria natural foram, respectivamente: farinha de algaroba, 1,26; 1,46; 1,74 e 1,73; farelo de arroz desengordurado, 1,21; 1,37; 2,22 e 2,22; farelo de arroz integral, 2,51; 2,70; 3,09 e 2,79; farelo de resíduo incubatório, 1,29; 1,37; 1,63 e 1,47; torta de dendê, 1,40; 1,69; 2,08 e 1,91; semente de guar moída, 0,94; 1,29; 1,37 e 1,33; farinha de mandioca integral, 2,82, 3,01, 3,34 e 3,27; farelo de raspa mandioca, 1,40, 1,76, 2,64 e 2,65; farinha de glúten milho, 3,53, 3,62, 4,33 e 3,95; milho moído, 3,04, 3,24, 3.65 e 3,50; farinha de peixe, 2,65, 2,22, 2,57 e 2,50; farelo de soja, 2,08, 2,17, 2,65 e 2,51; sorgo moído de alto tanino, 2,47, 2,75, 3,04 e 3,02; sorgo moído de baixo tanino, 2,90, 3,10, 3,47 e 3,38, e farelo de trigo, 1,26, 1,50, 2,06 e 1,88. Em função da correção dos valores energéticos pelas perdas endógenas e metabólicas, os valores de EMV e EMVn foram superiores aos de EMA e EMAn

    Efeito de níveis de metionina sobre o número de furos do disco germinal de ovos de codornas.

    Com o objetivo de predizer resultados de incubatório, avaliou-se o número de furos, feitos por espermatozoides, próximos ao disco germinal de ovos de codornas que receberam diferentes níveis de metionina na dieta, formulada à base de milho e farelo de soja, sendo os tratamentos: T1 = sem adição de metionina, somente a aportada pelos alimentos, T2 = inclusão de metionina estabelecida de acordo com Rostagno et al. (2011) para a espécie e T3 = inclusão de 20% superior à recomendada para a espécie (T2). Os ovos foram coletados, processados e o número de furos avaliado. Este trabalho não encontrou diferença significativa para os níveis de metionina testados. With the aim to predict hatching results, the number of sperm holes in the germinal disc area of Japanese quail eggs submitted to different dietary methionine content were counted. Treatments were stablished as: T1 = no supplementary methionine (just from the ingredients content), T2 = methionine content according to Rostagno et al. (2011), and T3 = T2 plus 20% additional methionine. The eggs were collected, processed, and the number of holes in the germinal disc area were recorded. No significant difference was observed for the dietary methionine levels tested

    Superheavy nuclei in selfconsistent nuclear calculations

    Get PDF
    The shell structure of superheavy nuclei is investigated within various parametrizations of relativistic and nonrelativistic nuclear mean field models. The heaviest known even-even nucleus 264Hs is used as a benchmark to estimate the predictive value of the models. From that starting point, doubly magic spherical nuclei are searched in the region Z=110-140 and N=134-298. They are found at (Z=114, N=184), (Z=120, N=172), or at (Z=126, N=184), depending on the parametrization.Comment: 16 pages RevTeX, 2 tables, 2 low resolution Gif figures (high resolution PostScript versions are available at http://www.th.physik.uni-frankfurt.de/~bender/nucl_struct_publications.html or at ftp://th.physik.uni-frankfurt.de/pub/bender ), submitted to Phys.

    Shell structure of superheavy nuclei in self-consistent mean-field models

    Get PDF
    We study the extrapolation of nuclear shell structure to the region of superheavy nuclei in self-consistent mean-field models -- the Skyrme-Hartree-Fock approach and the relativistic mean-field model -- using a large number of parameterizations. Results obtained with the Folded-Yukawa potential are shown for comparison. We focus on differences in the isospin dependence of the spin-orbit interaction and the effective mass between the models and their influence on single-particle spectra. While all relativistic models give a reasonable description of spin-orbit splittings, all non-relativistic models show a wrong trend with mass number. The spin-orbit splitting of heavy nuclei might be overestimated by 40%-80%. Spherical doubly-magic superheavy nuclei are found at (Z=114,N=184), (Z=120,N=172) or (Z=126,N=184) depending on the parameterization. The Z=114 proton shell closure, which is related to a large spin-orbit splitting of proton 2f states, is predicted only by forces which by far overestimate the proton spin-orbit splitting in Pb208. The Z=120 and N=172 shell closures predicted by the relativistic models and some Skyrme interactions are found to be related to a central depression of the nuclear density distribution. This effect cannot appear in macroscopic-microscopic models which have a limited freedom for the density distribution only. In summary, our findings give a strong argument for (Z=120,N=172) to be the next spherical doubly-magic superheavy nucleus.Comment: 22 pages REVTeX, 16 eps figures, accepted for publication in Phys.
