Valor nutritivo de silagens de híbridos de sorgo (Sorghum bicolor, l. Moench) em função de diferentes densidades de plantio.
Avaliou-se o valor nutritivo de silagens de dois híbridos de sorgo (AG 2005 e VOLUMAX), sob diferentes densidades de plantio (1,00m; 0,75m e 0,50m). Foram determinados os teores de proteína bruta e frações fibrosas. O delineamento experimental utilizado foi de blocos ao acaso com quatro repetições, sendo os tratamentos arranjados em esquema fatorial 3x2 (espaçamento x híbrido). As médias foram comparadas pelo teste de Tukey (P<0,05). Frações fibrosas da matéria seca não variaram com o aumento da densidade. O adensamento do espaçamento de plantio afetou o teor de proteína bruta das silagens dos híbridos AG 2005 e VOLUMAX de forma positiva, tendo apresentado média superior no espaçamento menor. Conclui-se que os híbridos estudados podem ser cultivados adensados, pois eleva o valor nutritivo. NUTRITIVE VALUE OF SILAGES FROM SORGHUM HYBRIDS (SORGHUM BICOLOR, L. MOENCH) WITH DIFFERENT PLANT DENSITY. Abstract: Nutritional values of two silages from the sorghum hybrids (AG 2005 and VOLUMAX) with different row spacing (1,00 m; 0,75 m and 0,50 m) were evaluated. Crude protein and fibrous fractions in dry matter were determined in silage. A randomized block design with four replicates was used. The treatments consisted in a factorial arrangement 3x2 (row spacing x hybrids). The means were compared by Tukey test (P<0.05). No effects of row spacing of the plant on fibrous fractions were found. Crude protein with silages increasing with narrow spacing. Concluding, these hybrids can be produced in high density, therefore your nutritive values are elevated

Quadrupole Moment Measurements of TSD1 and TSD2 Bands in \u3csup\u3e167\u3c/sup\u3eLu
The triaxial strongly deformed (TSD) bands in 167Lu were populated by the 123Sb(48Ca, 4n) reaction with a beam energy of 203 MeV. Gamma rays, requiring fivefold or more in prompt coincidence, were detected with the Gammasphere spectrometer. Of particular interests are TSD bands 1 and 2 which have previously been interpreted as zero phonon and one phonon wobbling bands, respectively. Using the Doppler shift attenuation method (DSAM), a preliminary transition quadrupole moment of 6.9+0.3−0.3 eb was extracted for the TSD1 band. Data analysis continues for TSD2 which is considerably more weakly populated

Spectroscopy around Ca
Expérience GANILInternational audienceAn experiment was performed to study excited states in neutron-deficient nuclei around Ca. A one-neutron knockout reaction was used to produce Ca ions from a Ca secondary beam, and in-beam -rays were measured. The energy in Ca is compared to the mirror nucleus S to deduce information on the isospin dependence of the nuclear force near the proton drip line. The energy of the first excited state in Ca and the cross section for the 1-neutron knock-out reaction from Ca at 45 · AMeV were obtained. Furthermore, for two other = −2 nuclei, S and Ar, the de-excitation of the first state has been observed
Evidence for octupole vibration in the triaxial superdeformed well of Lu164
High-spin states in Lu164 were populated in the Sb121(Ca48,5n) reaction at 215 MeV and γ-ray coincidences were measured with the Gammasphere spectrometer. Through this experiment the eight known triaxial superdeformed bands in Lu164 could be confirmed. Some of these bands were extended to higher as well as to lower spins. Evidence is reported for the first time for weak ΔI=1,E1 transitions linking TSD3 and TSD1. This observation may imply coupling to octupole vibrational degrees of freedom. The decay mechanism is different from the one observed in the neighboring even-N isotopes, which exhibit wobbling excitations built on the πi13/2 structure with E2(M1),ΔI=1 interband decay. An additional sequence decaying at high spin into TSD1 was observed up to Iπ=(50-). This band has a constant dynamic moment of inertia of ∼70 2MeV-1 and an alignment that is ∼2 larger than that found for TSD1. A revision of the assumed spin-parity-assignment of TSD2 is based on the observed decay-out to normal-deformed structures. The parity and signature quantum numbers of TSD2 are now firmly assigned as (π,α)=(+,0), in disagreement with the former assignment of (π,α)=(-,1), which was based on the assumption that TSD2 is the signature partner of TSD1. TSD1 and TSD2 show an alignment gain at ω∼0.67 and 0.60 MeV, respectively. In TSD1 the involvement of the j15/2 neutron orbital is suggested to be responsible for the high-frequency crossing
Collective and noncollective excitations in 122Te
High-spin states in 122Te were populated in the reaction 82Se(48Ca, α4n)122Te at a beam energy of 200 MeV and γ-ray coincidences were measured with the Gammasphere spectrometer. The previously known level scheme was extended to considerably higher spin. Maximally aligned states and several high-energy transitions feeding into some of these levels were observed. In addition, seven collective high-spin bands were discovered for the first time in this nucleus. The experimental results are compared with cranked Nilsson-Strutinsky model calculations and possible configuration assignments to the new high-spin structures are discussed
High-spin spectroscopy in Xe125
Levels excited up to 39.8 MeV and 119/2 units of angular momentum have been populated in Xe125 by the 82Se(Ca48,5n)Xe125 reaction. High-fold γ-ray coincidence events were measured using the Gammasphere Ge detector array. Nine regular rotational bands extending from levels identified previously up to almost 60ℏ have been identified, and three of these have been connected to low-lying levels having well-established spins and parities. Configurations have been assigned to six of the bands based on alignment properties, band crossings, and comparison with theoretical cranked shell model calculations (CSM). Transition quadrupole moments have been measured for these bands in the spin range 31-55ℏ and were found to be in agreement with the CSM calculations. The corresponding quadrupole deformation ε2 ranges from 0.28 to 0.34 at a γ deformation of 0° and from 0.29 to 0.36 at a γ value of 5°
Noncollective aligned and antialigned states in I125
High-spin states in I125 were populated using the reaction Se82(Ca48,p4n) at a beam energy of 200 MeV and γ-ray coincidence events were acquired with the Gammasphere spectrometer. The level scheme of I125 was extended considerably. In particular, maximally aligned states involving all eleven particles outside the Sn114 core were observed. Comparison with cranked Nilsson-Strutinsky calculations suggests that three of these states are the final Imax states in terminating bands with all spin vectors aligned along a common axis. In two of these, one spin vector is antialigned and points in the opposite direction. In one of the states two spin vectors are antialigned. This is the first observation of a state with such a structure
Highly deformed high-spin band in 125I
High-spin states in 125I have been investigated using the reaction 82Se(48Ca,p4n) at a beam energy of 200 MeV and γ-ray coincidence events were detected using the Gammasphere spectrometer. A deformed rotational band, extending up to Iπ=95/2-, was observed for the first time in a heavier odd-A iodine nucleus. The characteristics of the band are very similar to those of the highly deformed bands observed recently in neighboring nuclei and it is essentially identical to one of the previously known bands in 126Xe. The experimental results are compared to cranked Nilsson-Strutinsky calculations and possible configurations for the band are discussed
