The mean lifetimes of ten states in ${}^{133}\mathrm{Nd}$ excited via the reaction ${}^{104}\mathrm{Pd}{(}^{32}\mathrm{S},2pn)$ at $E_{{32}_{\mathrm{S}}}=135\mathrm{}$ MeV were measured by means of the recoil-distance Doppler-shift method. The spectra obtained by setting a gate on the shifted component of a transition directly feeding the level of interest were analyzed within the framework of the differential decay-curve method. The intraband transition strengths are compared to calculations within the particle plus rotor model which reveal differences in the quadrupole deformations $\epsilon$ and $\gamma$ of the bands studied.
