    Quadrupole shape invariants in the interacting boson model

    Get PDF
    In terms of the Interacting Boson Model, shape invariants for the ground state, formed by quadrupole moments up to sixth order, are studied in the dynamical symmetry limits and, for the first time, over the whole structural range of the IBM-1. The results are related to the effective deformation parameters and their fluctuations in the geometrical model. New signatures that can distinguish vibrator and gamma-soft rotor structures, and one that is related to shape coexistence, are identified.Comment: 10 pages, ReVTeX, epsf, 2 Postscript figures include

    Sub-barrier capture with quantum diffusion approach: actinide-based reactions

    Full text link
    With the quantum diffusion approach the behavior of capture cross sections and mean-square angular momenta of captured systems are revealed in the reactions with deformed nuclei at subbarrier energies. The calculated results are in a good agreement with existing experimental data. With decreasing bombarding energy under the barrier the external turning point of the nucleusnucleus potential leaves the region of short-range nuclear interaction and action of friction. Because of this change of the regime of interaction, an unexpected enhancement of the capture cross section is expected at bombarding energies far below the Coulomb barrier. This effect is shown its worth in the dependence of mean-square angular momentum of captured system on the bombarding energy. From the comparison of calculated and experimental capture cross sections, the importance of quasifission near the entrance channel is shown for the actinide-based reactions leading to superheavy nuclei.Comment: 11 pages, 16 figures, Regular Articl

    The purpose of this paper is to evaluate the primary databases of zootechnical records in western Siberia. The object of the study was the records on milk productivity (milk yield during the whole lactation, milk fat content, milk protein content, amount of milk fat, amount of milk protein), duration of lactation (service period, dry period, inter-breeding period), age of the first fruitful insemination and information on the origin of 20,000 Holstein cows. The validity of the raw data was assessed by assuming a Gaussian distribution without significant human influence. For this purpose, the Anderson-Darling test and corresponding visualization using histograms and quantile-quantile plots were applied. The list of traits of milk production was based on the values of the Anderson-Darling criterion. The authors found that the highest levels of this criterion were correlated with milk fat and protein. And the indicator Β«milk yieldΒ» was practically absent from the list of traits of dairy productivity. These results can be explained by the fact that in most enterprises, the value of milk yield was higher than the appraisal threshold values. An analysis of the genealogical trees of the studied breeding enterprises was carried out, along with the use of statistical criteria. This analysis revealed the inappropriate assignment of several dozen of offspring to a single mother. Thus, the presented approach can be used to identify outliers associated with human factors. And it can also be related to improper methodological support of the sampling process and errors in the work of the laboratories of selective milk quality control associated with the sampling and delivery of samples.ЦСлью настоящСй Ρ€Π°Π±ΠΎΡ‚Ρ‹ являСтся ΠΎΡ†Π΅Π½ΠΊΠ° Π±Π°Π· Π΄Π°Π½Π½Ρ‹Ρ… ΠΏΠ΅Ρ€Π²ΠΈΡ‡Π½ΠΎΠ³ΠΎ зоотСхничСского ΡƒΡ‡Ρ‘Ρ‚Π° Π² Π—Π°ΠΏΠ°Π΄Π½ΠΎΠΉ Π‘ΠΈΠ±ΠΈΡ€ΠΈ.

    The characteristic of bulls-producers of red breeds of OAO Barnaulskoe breeding enterprise on the quality of sperm and its resistance to cryopreservation are presented. The breeding enterprise has examined samples of water, soil, feed for the content of heavy metals. In the studied samples, no excess of the LOC was found. The research results were processed on a PC using population statistics methods. Angler bulls produced the largest amount of ejaculates unsuitable for cryopreservation. It is 20.6%. According to this indicator, they surpassed the producers of red Danish and red steppe breeds by 4.1-7.8%. The animals of the latter breed showed the smallest amount (1.7%) of ejaculates rejected after defrost. In Angler bulls, this indicator was 5.95%, in red Danish bulls it was 2.95%, which is 3.52 and 1.75 times higher than in red steppe breeders (P <0.01-0.001). Significant differences were established between individual bulls of the red steppe breed in the number of ejaculates rejected before cryopreservation (2.84-22.29%) and after defrost (0-7.09%). The differences between breeds in the frequency of rejected ejaculates before freezing and after cryopreservation indicate a certain role of heredity in the resistance of animals for these indicators. Spearman’s rank correlation coefficient between these traits was 0.312. It indicates the possibility of preliminary assessment and selection of bulls according to the first indicator. But the final assessment of the bull-producers can be made by the frequency of rejected ejaculates after thawing. We propose to consider the issue of additional accounting in breeding programs for the resistance of the seed of bulls-producers to cryopreservation.ΠŸΡ€ΠΈΠ²Π΅Π΄Π΅Π½Π° характСристика Π±Ρ‹ΠΊΠΎΠ²-ΠΏΡ€ΠΎΠΈΠ·Π²ΠΎΠ΄ΠΈΡ‚Π΅Π»Π΅ΠΉ красных ΠΏΠΎΡ€ΠΎΠ΄ ОАО ΠŸΠ»Π΅ΠΌΠΏΡ€Π΅Π΄ΠΏΡ€ΠΈΡΡ‚ΠΈΠ΅ Β«Π‘Π°Ρ€Π½Π°ΡƒΠ»ΡŒΡΠΊΠΎΠ΅Β» ΠΏΠΎ качСству спСрмы ΠΈ устойчивости Π΅Ρ‘ ΠΊ криоконсСрвации.
