A≈160质量区奇A核的形状演化效应
Structure Evolution in Odd-A Nuclei Around A≈1 60
摘要
Abstract
Objective]The paper aims at studying the structure evolution of the odd-A nuclei withA≈ 160 at high spin states.[Methods]Based on the experimental data from Nuclear Data Center National,the E-Gamma Over Spin(E-GOS)curves after correction were used firstly to investigate the structure evolution in the odd-Anuclei withA≈160 as a function of spin.[Re-sults]The nuclear shape is closely related to the neutron configuration,and the polarizing effect would begin to influence the core as valence nucleons start to fill high j neutron orbitals with increasing spin.Furthermore,it is founded that there is a clear structure evolution at high spin states of Yb isotopes based on the E-GOS characteristics.Namely,the Yb isotopes display a vi-brational character at low spins,whereas at higher spins they have a rotational pattern.[Conclu-sion]The phenomena of structure evolution were found in the odd-Anuclei withA≈ 160.关键词
