Abstract
The systematic dependence of Grodzins product E(2+1)*B(E2)↑ on the nucleonic promiscuity factor, i.e. P-factor = (Np Nn)/(Np + Nn), is studied in the Z = 50−82, N = 82−126 major shell space. The anomalous behaviour is noticed at N = 88−90, where the Grodzins product fails to maintain the constancy corresponding to P ≥ 4. The nuclei for P ≥ 4 region are recognised for enhanced collectivity, where p−n interaction is of the order of ~250 keV and it begins to dominate the pairing interaction of ~1 MeV. The P-factor also resolves the anomaly of not obtaining smooth universal Casten curve in Np Nn scheme. The approximate constancy in Grodzins product is noticed for well deformed nuclear region. The relation between Grodzins product and P-factor has been studied for the first time.
期刊介绍：
Today, nuclear reactors generate nearly one quarter of the electricity in nations representing two thirds of humanity, and other nuclear applications are integral to many aspects of the world economy. Nuclear fission remains an important option for meeting energy requirements and maintaining a balanced worldwide energy policy; with major countries expanding nuclear energy"s role and new countries poised to introduce it, the key issue is not whether the use of nuclear technology will grow worldwide, even if public opinion concerning safety, the economics of nuclear power, and waste disposal issues adversely affect the general acceptance of nuclear power, but whether it will grow fast enough to make a decisive contribution to the global imperative of sustainable development.
