| 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 p
1/2 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.
