Abstract
The electromagnetic features of the isomers in the isotopes are reproduced by numerically optimized shell-model wave functions. A sudden phase change of the wave functions at is identified and further confirmed by the evolution of , values. This phase change gives rise to different linear relations for the and values with and , as needed to reproduce the experimental data. The particle-hole transformation properties for neutrons in a well-isolated subshell involving degenerate , , , and orbits is suggested as a possible explanation for this phase change.
