Abstract
- The $\bar{\nu}_e + {^2{\rm H}} \rightarrow e^+ + n + n$, $\nu_e + {^2{\rm H}} \rightarrow e^- + p + p$, $\bar{\nu}_l + {^2{\rm H}} \rightarrow \bar{\nu}_l + {^2{\rm H}}$, $\nu_l + {^2{\rm H}} \rightarrow \nu_l + {^2{\rm H}}$, $\bar{\nu}_l + {^2{\rm H}} \rightarrow \bar{\nu}_l + p + n$, $\nu_l + {^2{\rm H}} \rightarrow \nu_l + p + n$, $\bar{\nu}_e + {^3{\rm He}} \rightarrow e^+ + {^3{\rm H}}$, $\bar{\nu}_l + {^3{\rm He}} \rightarrow \bar{\nu}_l + {^3{\rm He}}$, $\nu_l + {^3{\rm He}} \rightarrow \nu_l + {^3{\rm He}}$, $\bar{\nu}_l + {^3{\rm H}} \rightarrow \bar{\nu}_l + {^3{\rm H}}$, $\nu_l + {^3{\rm H}} \rightarrow \nu_l + {^3{\rm H}}$, $\bar{\nu}_e + {^3{\rm He}} \rightarrow e^+ + n + d$, $\bar{\nu}_e + {^3{\rm He}} \rightarrow e^+ + n + n + p$, $\bar{\nu}_l + {^3{\rm He}} \rightarrow \bar{\nu}_l + p + d$, $\bar{\nu}_l + {^3{\rm He}} \rightarrow \bar{\nu}_l + p + p +n$, $\nu_l + {^3{\rm H}} \rightarrow \nu_l + n + d$ and $\nu_l + {^3{\rm H}} \rightarrow \nu_l + n + n + p$ reactions ($l= e, \mu, \tau$) are studied consistently in momentum space for (anti)neutrino energies up to 300 MeV. For most of these processes we provide predictions for the total cross sections and in the case of the (anti)neutrino-$^3$He and (anti)neutrino-$^3$H inelastic scattering we compute examples of essential response functions, using the AV18 nucleon-nucleon potential and a single-nucleon weak current operator. For the reactions with the deuteron we study relativistic effects in the final state kinematics and compare two-nucleon scattering states obtained in momentum and coordinate spaces. Our results from momentum space are compared with the theoretical predictions by G.Shen et al., Phys. Rev. C 86, 035503 (2012). The observed disagreement can be attributed to the differences in kinematics and in the weak current operator.<br />Comment: 31 pages, 18 figures in 49 eps files
