摘要:

在Fayans等人的能量密度泛函的有限费米系统自洽理论中,采用两组固定参数DF 3和DF 3-a,计算了半魔铅、锡同位素和$N=50,N=82$同位素奇邻体的四极矩.它们不同的自旋轨道和有效张量力参数,后者是显着更大的DF 3-a功能。两个泛函的结果是相当不同的。的功能DF 3-a导致四极矩在合理的协议与实验的大多数核检查。

英文摘要:

The quadrupole moments of odd neighbors of semi-magic lead and tin isotopes and $N=50,N=82$ isotones are calculated within the self-consistent Theory of Finite Fermi Systems based on the Energy Density Functional by Fayans et al. Two sets of parameters, DF3 and DF3-a, fixed previously are used. They differ by the spin-orbit and effective tensor force parameters, the latter being significantly bigger in the DF3-a functional. Results for the two functionals turned out to be rather different. The functional DF3-a leads to quadrupole moments in reasonable agreement with the experimental ones for most nuclei examined.
