Abstract
The electric-octupole transition strengths from the first state to the ground-state transition in shell even-even nuclei with to 40 are investigated within the shell model framework using the effective (0+1) PSDPF interaction. For this type of transition, new effective charges for protons and neutrons have been determined. Their values 1.36 e for protons and 0.48 e for neutrons are close to those obtained previously for electric-quadrupole transitions in shell nuclei. The calculated transition strengths from the transitions are compared to a compilation of experimental data for even-even nuclei throughout the shell.
