Energy levels of the nucleus248Bk

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The ambiguities and contradictions in presently available experimental information on the energy levels of the doubly odd deformed nucleus248Bk are sought to be cleared through calculation of the band head energies of the two-particle states based on evaluation of the residualn-p interaction energy for a zero range interaction. The applicability of the Gallagher-Moszkowski rule for the relative ordering of the spin triplet and singlet states is critically examined. It is concluded that the 8− state from the {7/2+[633]p; 9/2−[734]n configuration is the long lived isomer and forms the ground state of this nucleus. The 1− state of the same configuration is the short lived isomer and an excited state in accordance with the GM rule and so is the 6+ state of the {3/2−[521]p; 9/2−[734]n configuration. The expected location of 20 two particle states comprising 10 GM pairs is calculated and compared with the available experimental information.
