相对论平均场理论对Pt同位素形状演化的研究
Analysis of shape evolution for Pt isotopes with relativistic mean field theory
摘要
Abstract
The relativistic mean field theory is used to investigate the shape evolution of Pt isotopes. The calculated binding energy and deformation parameter/32 are consistent with those obtained in experiment. The potential energy surfaces and the single particle levels show the shape evolution for Pt isotopes. From N = 88 to N = 126, the shapes for Pt nuclei evolve from spherical shapes to X(5), and then to shapes of stable quadruple deformation, finally back to the spherical shapes. In detail, 166-172^Pt are spherical. 174^pt and 192-196^pt possess the X(5) symmetry. 176-190^pt are deformed nuclei. 204^Pt holds spherical shape. These results in agreement with the experimental observations.关键词
