Pion absorption channels in 4He at 114 MeV

Multiparticle coincidences following the absorption on π+ on 4He were measured using a liquid helium target and a large solid angle detector. Results of the reaction 4He(π+, x ...) will be presented. The cross sections and angular distributions of all possible processes leading to pp, ppp, ppd, and pd final states were extracted with the help of Geant Monte Carlo simulations modified specifically for this experiment
