Abstract
Effective charges are calculated for protons and neutrons in the region
of mass 90. It is found that their magnitudes differ appreciably
depending on whether the proton p1/2 shell is empty or full. The
calculated values are compared with values deduced from nuclei with
simple configurations, and from a fit to N=50 data. The empirical
values are used in shell-model calculations of quadrupole moments of
N=50-58 nuclei.
