Pion excitation functions in proton-nucleus collisions, from the absolute threshold to 500 MeV, have been measured with 1 MeV beam energy resolution at the CELSIUS storage ring, operating in slow ramping mode. Total yields, angular distributions, and target mass dependence of pi(+) production are generally reproduced well by QMD calculations. The pi(+)/pi(-) ratios are not reproduced equally well, obviously because the detailed description of the pion interaction with the Coulomb field is very delicate. RI BELLINI, Vincenzo/B-1239-2012

Abstract:	Pion excitation functions in proton-nucleus collisions, from the absolute threshold to 500 MeV, have been measured with 1 MeV beam energy resolution at the CELSIUS storage ring, operating in slow ramping mode. Total yields, angular distributions, and target mass dependence of pi(+) production are generally reproduced well by QMD calculations. The pi(+)/pi(-) ratios are not reproduced equally well, obviously because the detailed description of the pion interaction with the Coulomb field is very delicate. RI BELLINI, Vincenzo/B-1239-2012
