Formula omitted] transitions of 40Sc using Tamm–Dancoff approximation

Abstract

Within a developed particle-hole approach we have studied the β+/EC transitions of 40Sc → 40Ca. The wave functions of nuclear excited states have been calculated using the Tamm-Dancoff approximation. The mean field phenomenological potential introduced recently by Salamon and Vertse has been used to find the single particle states of the nucleons. The surface delta interaction has been adopted as the residual interaction between valance nucleons. The excited states energies of 40Sc and 40Ca, branching ratios, partial decay half-lives, total decay half-life, and logft12 values have been calculated and reasonable agreement with experimental data have been achieved.
