Measurement of<i>E0</i>transitions in neutron-rich nuclei near<i>A</i>=100

Abstract

Conversion electrons have been measured for E0 transitions between the first excited ${0}^{+}$ states and the ground states of $^{100}\mathrm{Mo}$, $^{102}\mathrm{Mo}$, $^{106}\mathrm{Ru}$, $^{108}\mathrm{Pd}$, $^{110}\mathrm{Pd}$, and $^{112}\mathrm{Pd}$. The ${\ensuremath{\rho}}_{21}^{2}$ and ${X}_{\mathrm{ijk}}$ values are calculated from the measured E0/E2 branching ratios and level lifetimes that were either measured in this experiment or obtained from the literature. The results are discussed briefly in terms of neutron-proton interacting boson model mixed-configuration calculations and intruder states.
