Electric monopole (E0) transitions between low lying levels in ${}_{}{}^{102}{}_{}{}^{}\mathrm{Ru}$, populated in the decay of ${}_{}{}^{102}{}_{}{}^{}\mathrm{Rh}$, have been investigated by means of conversion-electron and γ-ray spectroscopy. Values or upper limits for the ratio X(E0/E2) of E0 to E2 reduced transition probabilities have been derived for the transitions from the $0_3^{+}$ and $0_2^{+}$ to the $0_1^{+}$ and $2_1^{+}$ states and for the $2_2^{+}$→$2_1^{+}$ transition. The experimental results are discussed in the frame of a schematic interacting boson model.
