The s-wave isoscalar amplitude for 7rcr scattering in a nuclear medium is evaluated using a nonperturbative unitary coupled channels method and the standard chiral Lagrangians. The method has proved successful to describe the 7rTr properties in the scalar-isoscalar channel up to 1.2 GeV, giving rise
A simple approximation to the inelastic N-N\* transition form factor which was treated formally in the previous paper is developed from the N/D approach outlined there. Numerical calculations based on the approximation derived from the N/D method on the one hand, and directly from the analytically-c
