Electron and Muon production cross sections in quasielastic $ u(bar u)$-Nucleus scattering for $E_ u < 1~GeV$

In this work, we have studied (anti)neutrino induced charged current quasielastic scattering from some nuclear targets in the energy region of $E_ u < 1~GeV$. Our aim is to confront electron and muon production cross sections relevant for $ u_mu leftrightarrow u_e$ or $bar u_mu leftrightarrow bar u_e$ oscillation experiments. The effects due to lepton mass and its kinematic implications, radiative corrections, second class currents and uncertainties in the axial and pseudoscalar form factors are calculated for (anti)neutrino induced reaction cross sections on free nucleon as well as the nucleons bound in a nucleus where nuclear medium effects influence the cross section. For the nuclear medium effects we have taken som
