Abstract

Prompt γ rays from π interactions with F19, Al27, and V51 near the Δ(1232) resonance were detected. Deexcitation γ rays from residual nuclei formed by single and multiple nucleon removal and by inelastic and charge exchange scattering were identified, and cross sections for excitation of residual states were determined. Nuclear recoil momenta were determined from observed Doppler broadening. Where possible, the cross sections were corrected for γ feeding from higher states. The results are compared with the results of previous experiments and of intranuclear cascade/evaporation code calculations.
