It has recently been proposed that ${}^{92}_{41}$Nb and ${}^{98}_{43}$Tc mayhave been formed in the $\nu$-process. We investigate the neutrino inducedreactions related to the $\nu$-process origin of the two odd-odd nuclei. Themain neutrino reactions for ${}^{92}_{41}$Nb are the charged-current (CC)$^{92}$Zr($\nu_e,e^{-}$)$^{92}$Nb and the neutral-current (NC) $^{93}$Nb(${\nu}({\bar \nu}), {\nu}^{'} ({\bar \nu})^{'}$ n)$^{92}$Nb reactions. The mainreactions for ${}^{98}_{43}$Tc, are the CC reaction$^{98}$Mo($\nu_e,e^-$)$^{98}$Tc and the NC reaction $^{99}$Ru(${\nu} ({\bar\nu}), {\nu}^{'} ({\bar \nu})^{'}$ p)$^{98}$Tc. Our calculations are carriedout using the quasi-particle random phase approximation. Numerical results arepresented for the energy and temperature dependent cross sections. Since chargeexchange reactions by neutrons may also lead to the formation of${}^{92}_{41}$Nb and ${}^{98}_{43}$Tc, we discuss the feasibility of the$^{92}$Mo(n,p)$^{92}$Nb and $^{98}$Ru(n,p)$^{98}$Tc reactions to produce thesenuclei.
