Neutrino induced reactions related to the -process nucleosynthesis of Nb and Tc
It has recently been proposed that Nb and Tc may
have been formed in the -process. We investigate the neutrino induced
reactions related to the -process origin of the two odd-odd nuclei. The
main neutrino reactions for Nb are the charged-current (CC)
Zr()Nb and the neutral-current (NC) Nb( n)Nb reactions. The main
reactions for Tc, are the CC reaction
Mo()Tc and the NC reaction Ru( p)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
Nb and Tc, we discuss the feasibility of the
Mo(n,p)Nb and Ru(n,p)Tc reactions to produce these
nuclei.Comment: 21 pages, 8 figure
