摘要：

The unpolarised differential cross section and deuteron tensor analysing power t20 are estimated for the dp to 3He pi 0 reaction in the forward and backward directions within a two-body cluster model for the 3He nucleus. All the qualitative features of the low-energy data, such as the rapid rise in the forward/backward asymmetry and the oscillation in t20 as the energy increases, are well reproduced in terms of amplitudes deduced from pp to d(d*) pi . At higher energies the forward data are still well described although one of the amplitudes in the backward direction is seriously underpredicted.
