In the present study of charged pion photoproduction from nuclei, the validity of the impulse approximation is assumed and the free single nucleon photoproduction amplitudes of Chew, Goldberger, Low and Nambu, are used. The angular distributions are analysed. Successively improved wave functions for the ground and excited states of the nuclei are used to study the nuclear structure effects, on the cross section, since the effect of final state interactions on the pion angular distributions has already been studied. The thesis consists of two parts, Part I deals with photoproduction of charged pions from nucleons, and Part II deals with the standard, polarised and modified 'polarised cluster model wave functions'. The polarised cluster model wave function, in whose relative motion part, incorporated with a shell model node, is referred to as the 'modified polarised cluster model', throughout this thesis.
