Pion Absorption in Helium with the LADS Detector

Part of the Few-Body Systems book series (FEWBODY, volume 9)


Investigations on π-absorption on Helium reveal a substantial part of the absorption cross section to be multi-nucleon absorption. A careful search for different reaction mechanisms shows clear signatures of initial state interaction, whereas most of the multi-nucleon absorption follows a phase space like distribution. In comparable conditions the signatures look alike for either 3He and 4He. Fits of Monte Carlo simulations to the data give first results on the partial cross sections in 3He.
