Neutrino induced reactions related to the $\nu$-process nucleosynthesis of ${}^{92}$Nb and ${}^{98}$Tc

Abstract

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