The cross section for the pd-->He-3 pi(+)pi(-) reaction has been measured i
n 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 when it is assumed that the reaction is dominated by p-wa
ve pi(+)pi(-) pairs. This is in complete contrast to the results of inclusi
ve measurements at somewhat higher beam energies which show a strong s-wave
ABC enhancement at low pi pi masses. [S0556-2813(99)51111-4].
