THE log(ft) VALUES IN SPHERICAL AND DEFORMED NUCLEI FOR SOME ODD-A GERMANIUM ISOTOPES

Abstract

The log(ft) values of the allowed 𝛽± decay between odd-A spherical and deformed nuclei are studied for germanium isotopes in this paper. The Pyatov Method (PM) and the Schematic Model (SM)) are used to the GT strength distributions, including the schematic residual spin-isospin interaction between nucleons in the particle-hole and particle-particle channels. Particle- hole and particle-particle interaction parameters are calculated respectively with 𝒳𝑝ℎ 𝐺𝑇 = 5.2 𝐴0.7 MeV and 𝒳𝑝𝑝 𝐺𝑇 = 0.58 𝐴0.7 MeV. Deformed Woods-Saxon potential is used in calculations of single-particle energies and wave functions. The results are also compared with previous experiment values wherever available
