Dover, Carl B.

The role of the Pauli principle in pion-nucleus scattering is studied using many-body theory with propagators. The objective is to calculate the pion self energy in the nucleus from an effective ..pi..N amplitude which is density dependent. It is concluded that the Pauli effect on the optical potential is small (5% level), that first order hole line expansion for the effective amplitude is inappropriate, and that particle and hole propagation must be treated symmetrically. 2 references.
