Coherent pion production in nucleus-nucleus reactions

Description

Results from two earlier experiments searching for coherent pions are discussed. The 12C (12C, 12C) reaction has been studied at GANIL at 95 MeV/nucleon giving an upper limit for the cross section (≤60nb). Recent measurements performed at SATURNE using the 12C(3He,t) reaction at 2 GeV clearly show a strong indication for coherent pion production and a large shift of the Δ-peak observed in the coherent channel. Both reactions probe the spin-longitudinal response of nuclei. In the intermediate region, near pion production threshold, the distortion effects are less important than at low energy and moreover, the coherence effects might be enhanced.
