Abstract

We have calculated the strength functions of the Gamow-Teller transition processes from mirror pairs ⁴⁶Ti–⁴⁶Cr and ⁵⁰Cr–⁵⁰Fe to the odd-odd N = Z nuclei ⁴⁶V and ⁵⁰Mn. The calculations are carried out in fp model space with shell model diagonalization method. Calculations are compared with experimental observations. We have also discussed the effects of isospin symmetry breaking on the analogous transitions.
