Abstract

Abstract: A systematic dependence of shape fluctuation energy product SFE * B (E2) ↑ and rotational energy product ROTE * B (E2) ↑ on the valence nucleon product N p N n 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 N p N n . A relative rise, on the other hand, is observed in the product ROTE * B (E2) ↑ plotted against N p N n 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 N p N n .
