Lifetimes of low-spin excited states in $^{102}\mathrm{Mo}$ populated a $^{100}\mathrm{Mo}(^{18}\mathrm{O},\phantom{\rule{0.16em}{0ex}}^{16}\mathrm{O})^{102}\mathrm{Mo}$ two-neutron transfer reaction were measured using the recoil-distance Doppler-shift technique at Cologne FN Tandem accelerator. ${2}_{1}^{+}$, ${4}_{1}^{+}$, ${6}_{1}^{+}$, ${0}_{2}^{+}$, ${2}_{\ensuremath{\gamma}}^{+}$, ${3}_{\ensuremath{\gamma}}^{+}$ and one upper limit for lifetime ${4}_{\ensuremath{\gamma}}^{+}$ state obtained. The energy levels deduced electromagnetic transition probabilities are compared with those obtained within mapped interacting boson model framework microscopic input from Gogny mean-field calculations. With newly signatures more detailed insight $\ensuremath{\gamma}$ softness shape coexistence is possible discussed context $Z\ensuremath{\approx}40$ $N\ensuremath{\approx}60$ region. nucleus follows soft trend Mo isotopes. properties ${0}_{2}^{+}$ indicate, contrast predictions, which also occurs other $N=60$ isotones.
