Abstract: (APS)
The cross section for the pd3He π+π− reaction has been measured in a kinematically complete experiment at a c.m. excess energy of Q=70 MeV. The striking energy and angular distributions are reproduced in a simple model calculation where it is assumed that the reaction is dominated by p-wave π+π− pairs. This is in complete contrast to the results of inclusive measurements at somewhat higher beam energies which show a strong s-wave ABC enhancement at low ππ masses.- p deuteron: nuclear reaction
