Popis:	The yrast band of the $N=Z$ nucleus ${}^{84}\mathrm{Mo}$ has been extended up to the ${10}^{+}$ state. Its moment of inertia varies smoothly up to this state (rotational frequency 0.6 MeV). The new data confirm the systematic delay of the particle alignment frequency in $N=Z$ nuclei with respect to the neighboring $NgZ$ nuclei, which has been suggested as a signature of the neutron-proton pairing interaction. Projected shell model calculations performed for the heaviest $N=Z$ nuclei studied so far, ${}^{84}\mathrm{Mo}$ and ${}^{88}\mathrm{Ru},$ predict that the confirmation of a possible enhancement of the neutron-proton residual interaction requires the observation of still higher spins in these nuclei.
