Abstract
Pionic X-rays and pi(0) decays were measured for gas mixtures of H-2/D-2/CH 4+SF6/Ar and the individual pure gases. Chemical effects on the pion transf er process from pionic hydrogen to other atoms were revealed by the pionic X-ray spectrum. The changes of the intensity patterns of pionic X-rays were compared with the predictions by a cascade calculation taking the transfer process into account. The mechanism of pion transfer process was discussed based on the results for gas phase and the previous ones for liquid phase.
