Weak Pion Production From Nuclei
  The charged current pion production induced by neutrinos in $^{12}{C}$, $^{16}{O}$ and $^{56}{Fe}$ nuclei has been studied. The calculations have been done for the coherent as well as the incoherent processes assuming $\Delta$ dominance and take into account the effect of Pauli blocking, Fermi motion and the renormalization of $\Delta$ in the nuclear medium. The pion absorption effects have also been taken into account.
