Abstract

The diagrams of the Tamm-Dancoff and random-phase approximations have been summed to calculate the effective charge in the 1s0d and 1p0f shells. The generally large RPA result for the effective charge is reduced to roughly the TDA one when the self-screening corrections to the particle-hole and ground-state correlation vertices are included. The screening corrections serve to suppress the collectivity of the isoscalar quadrupole core phonons and are particularly important for 40Ca where the isoscalar quadrupole mode is near collapse in the RPA using the bare particle-hole interaction. The qualitative rather than the quantitative effects of these and other corrections are stressed.
