摘要

A systematic dependence of shape fluctuation energy product SFE* B(E2) ↑ and rotational energy product ROTE* B(E2) ↑ on the valence nucleon product NpNn is carried out in the Z =50-82,N =82-126 major shell space.For the shape transitional nuclei,the product SFE*B(E2) ↑ drops to zero and becomes negative,indicating direct dependence on NpNn.A relative rise,on the other hand,is observed in the product ROTE*B(E2) ↑ plotted against NpNn for all the nuclei in Z =50-82 and N =82-126.In the N ＞ 104 region,large positive values of the product SFE* B(E2) ↑ are observed for the Pt nucleus,which indicates sphericity.A systematic study of the product SFE* B(E2) ↑ and ROTE* B(E2) ↑ with atomic number Z is also discussed.The products SFE* B(E2) ↑ and ROTE*B(E2) ↑ vary sharply with Z for the N =88 isotones.We discuss here for the first time the correlation between SFE* B(E2)↑ and ROTE* B(E2)↑ with valence nucleon product NpNn.
