Abstract

It has recently been proposed that 4192Nb and 4398Tc may have been formed in the ν-process. We investigate the neutrino induced reactions related to the ν-process origin of these two odd-odd nuclei. We find that the main neutrino reactions to produce 4192Nb are the charged-current (CC) 92Zr(ν e,e -)92Nb and the neutral-current (NC) 93Nb[ν(ν̄),ν′ (ν ̄ )′ n]92Nb reactions. Similarly, the main reactions for 4398Tc, are the CC reaction 98Mo(ν e,e -)98Tc and the NC reaction 99Ru[ν(ν̄),ν′ (ν ̄ )′p]98Tc. Our calculations are carried out using the quasiparticle 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 4192Nb and 4398Tc, we also discuss the feasibility of the 92Mo(n,p)92Nb and 98Ru(n,p)98Tc reactions to produce these nuclei.
