Calculation of energy spectra of pions in the reaction 12C(γ,π-p) on basis of the inproved model of the pion-nucleus interaction

The calculations of the correlation function on the emitting pion energy dependences for the 12C(γ,π-p) reaction with the bremsstrahlung spectrum of γ-quanta have been carried out. Gamma-quantum interaction with a nucleus is considered in the pulse approximation and the produced pion interaction is taken into consideration in the frameworks of the optical model with the help of which the satisfactory explanation of the data on the pion tained. The one-particle shell model is used for the description of the 12C ground state
