  A study of charged current induced anti-neutrino interactions from nuclei has
been done for the intermediate energy ($<2$GeV) anti-neutrinos and applied to
$^{12}$C, relevant for ongoing experiment by MiniBooNE collaboration. The
calculations have been done for the quasielastic and inelastic lepton
production as well as for the incoherent and the coherent pion production
processes. The calculations are done in local density approximation. In the
case of the quasielastic reaction the effects of Pauli blocking, Fermi motion
effects, renormalization of weak transition strengths in nuclear medium and the
Coulomb distortion of the outgoing lepton have been taken into account. For the
inelastic processes the calculations have been done in the $\Delta$ dominance
model and take into account the effect of Pauli blocking, Fermi motion of the
nucleon and renormalization of $\Delta$ properties in a nuclear medium. The
effect of final state interactions of pions is also taken into account. The
numerical results for the total cross sections for the charged current
quasielastic scattering and incoherent pion production processes are compared
with earlier experimental results available in Freon and Freon-Propane. It is
found that nuclear medium effects give strong reduction in the cross sections
leading to satisfactory agreement with the available data.
