摘要：

最近有人提出，${}^{92}_{41}$ Nb和${}^{98}_{43}$ Tc可能是在$ν$ -过程中形成的。我们研究了与两个奇-奇核的$ν$过程起源有关的中微子诱导反应。${}^{92}_{41}$ Nb的主要中微子反应是带电流（CC）$^{92}$ Zr（$ν_e,e^{-}$）$^{92}$ Nb和中性流（NC）$^{93}$ Nb（$ν ({\bar ν}), ν^{'} ({\bar ν})^{'}$ n）$^{92}$ Nb反应。${}^{98}_{43}$ Tc的主要反应是CC反应$^{98}$ Mo（$ν_e,e^-$）$^{98}$ Tc和NC反应$^{99}$ Ru（$ν ({\bar ν}), ν^{'} ({\bar ν})^{'}$ p）$^{98}$ Tc。我们的计算是使用准粒子无规相位近似。数值结果的能量和温度依赖的横截面。由于中子的电荷交换反应也可能导致${}^{92}_{41}$ Nb和${}^{98}_{43}$ Tc的形成，我们讨论了$^{92}$ Mo（n，p）$^{92}$ Nb和$^{98}$ Ru（n，p）$^{98}$ Tc反应产生这些核的可行性。

英文摘要：

It has recently been proposed that ${}^{92}_{41}$Nb and ${}^{98}_{43}$Tc may have been formed in the $ν$-process. We investigate the neutrino induced reactions related to the $ν$-process origin of the two odd-odd nuclei. The main neutrino reactions for ${}^{92}_{41}$Nb are the charged-current (CC) $^{92}$Zr($ν_e,e^{-}$)$^{92}$Nb and the neutral-current (NC) $^{93}$Nb($ν ({\bar ν}), ν^{'} ({\bar ν})^{'}$ n)$^{92}$Nb reactions. The main reactions for ${}^{98}_{43}$Tc, are the CC reaction $^{98}$Mo($ν_e,e^-$)$^{98}$Tc and the NC reaction $^{99}$Ru($ν ({\bar ν}), ν^{'} ({\bar ν})^{'}$ 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 ${}^{92}_{41}$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 these nuclei.
