Abstract

We have measured cross sections for the (π+,π±p) reactions on 3H, 4He, 6Li and 7Li in quasi-free kinematics at incident pion beam energy 500 MeV. An enhancement of the (π+,πp) cross section in this kinematics is observed. If this is interpreted as due to quasi-free scattering from preexisting Δ components of the nuclear wave function, the extracted probabilities are in agreement with theoretical expectations.
