Abstract

A simultaneous theoretical analysis of the polarization observables for negative pion photoproduction off the neutron and {sup 3}H, {sup 13}C and {sup 15}N is performed. A sensitivity of the target and recoil asymmetries to different ingredients of the theory (the Fermi-motion, the final state interaction and the nuclear model input) is investigated. An importance of the high (2 {Dirac_h} {omega} ) configurations in the ground nuclear states is shown. A possibility to extract additional information about the nuclear structure as well as about the behavior of the {Delta} isobar in nucleus is shown to exist. (author). 24 refs.; 6 figs.
