Pionska apsorpcija u 4He
This paper presents a large solid angle measurement of the positive pion absorption cross-section on 4He and its decomposition into partial channels. A large fraction of the absorption cross-section at incident pion kinetic energies of Tπ+ =70, 118, 162, 239, and 330 MeV is due to multinucleon channels.Daju se ishodi mjerenja pod velikim prostornim kutom udarnog presjeka za apsorpciju pozitivnih piona u He4 i razdjela na pojedine kanale. Velik dio apsorpcijskog udarnog presjeka za energije upadnih piona od Tπ+ =70, 118, 162, 239 i 330 MeV je posljedica višenukleonskih kanala
Pion absorption reactions on \chem{N}, \chem{Ar} and \chem{Xe}
The absorption of on \chem{Ar} was studied at
pion energies of 70, 118, 162, 239 and 330MeV, and on
\chem{N} and \chem{Xe} at 239MeV. Twenty-six absorption
reaction channels with at least two energetic charged particles
in the final state have been evaluated. Partial cross-sections
have been determined according to the number of protons, neutrons
and deuterons in the final state
