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 ${\rho }_{21}^2$ 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.
