Studies of ï°g9/2+ isomers in odd 67-79As nuclei by deep-inelastic collisions

Abstract

In this paper, we report systematic studies of single particle pg_9/2⁺ isomers in odd ^67-79As nuclei. We have calculated the energies of projectile-like fragments of odd ^67-79As in ⁷⁶Ge (635 MeV) + ¹⁹⁸Pt reactions. The theoretical calculations of projectile like fragments (PLFs) energies are compared with the experimental values. The mean lives, reduced transition probabilities, width of isomeric levels, and Weisskopf hindrance factors in odd ^67-79As nuclei are calculated. The excitation levels of 9/2⁺ and 5/2^- state as a function of mass number from odd ⁶⁷As to ⁷⁹As nuclei indicate maximum deformation at N=42. The systematic reduced transition probabilities B(M2) of odd ^67-79As nuclei are also investigated. The angular distributions of fragments energies of ⁷⁹As and its counterpart as a function of scattering angles are investigated.
