Measurements of the analyzing power in the two-nucleon transfer reaction ($\overrightarrow{t}, p$) have been carried out leading to ${}_{}{}^{98}{}_{}{}^{}\mathrm{Mo}$ and to the transitional nucleus ${}_{}{}^{102}{}_{}{}^{}\mathrm{Mo}$ where shape coexistence states are expected. Because of the sensitivity of the shapes of analyzing powers to the reaction mechanism, such data may be useful in determining the basic parentage of excited states in these nuclei through the interference of second order processes. A comparison of the ground state and strong excited $0^{+}$ state transitions shows no large differences in the shapes of analyzing powers nor are any observed in $L=2\mathrm{}$ transitions.

NUCLEAR REACTIONS ${}_{}{}^{96,100}{}_{}{}^{}\mathrm{Mo}(\overrightarrow{t}, p)$ $E=17\mathrm{}$ MeV; polarized beam; enriched targets: measured $\sigma (E_p, \theta )$, $A_y\left(\theta \right)$; DWBA; transitional nucleus description.
