Abstract

The microscopic effective charges in mirror nuclei ⁵¹Mn and ⁵¹Fe are investigated with the particle-vibration coupling model based on the self-consistent Skyrme-Hartree-Fock and continuum random-phase-approximation approaches. The isovector parts are predicted to be around 0.15, and the proton effective charges are around e_p^eff=1.25e, which is less than the empirical value of . The microscopic effective charges in neutron rich ⁵¹Mn are about 10% less than its proton rich mirror. These effective charges are combined with the shell model to calculate the reduced electric quadrupole transition probability B(E2) values in 51Mn and 51Fe. It turns out that the microscopic effective charges have reproduced the B(E2) values and its ratio in the terminating states well.
