✦ Synopsis

Scattering and absorption of pions by a nuclear target are treated together in a coupled channel theory. The theory is developed explicitly for the problem of pion scattering and absorption by a deuteron. The equations are presented in terms of the integral equations of three-body scattering theory. The method is then applied in an approximate form to calculate the contribution of pion absorption to the scattering length for pion-deuteron scattering. The sensitivity of the calculated results to the model assumptions and approximations is investigated. 477
