We have proposed the neutrino-process origin for 92Nb and reproduced the 92Nb abundance by SN models with assumed neutrino temperatures. Since the neutrino-nucleus interactions are one of key physics, we have calculated them by using QRPA models. We also suggest the possibility that 98Tc (T1/2=4.2 Myr) can be produced by the neutrino process. When the 98Tc abundance at SSF will be measured, we can constrain strongly neutrino temperatures.
