Abstract

We have studied the core-polarization effect on the 1s0d-shell single-particle electromagnetic quadrupole transitions due to coupling with the quadrupole giant resonances. The self-consistent Hartree-Fock + RPA method is applied for the calculations of the single-particle wave functions and the response functions of the giant resonances. The particle-vibration-coupling model is used to calculate the core-polarization effect in the vicinity of 16O and 40Ca. The effective coupling hamiltonian is determined by the SGII Skyrme-type interaction which is used in the HF + RPA and particle-vibration-coupling calculation. The results are discussed for the proton and neutron effective charges and for the longitudinal and transverse form factor for the 0d32−1 → 1s12−1 pro single-particle transition in 39K. Good agreement with recent longitudinal data for this transition is obtained.

      The microscopic origin has been traced back to the coupling between single-particle states and collective giant resonances. The core polarization charges were studied by microscopic particle-vibration (PV) models [23,28–31]. However, the polarization effects of core neutrons have not been studied by microscopic models.
