Abstract
Pion excitation functions in proton-nucleus collisions, from the absolute t hreshold to 500 MeV, have been measured with 1 MeV beam energy resolution a t the CELSIUS storage ring, operating in slow ramping mode. Total yields, a ngular distributions, and target mass dependence of pi(+) production are ge nerally 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.
