Recent results from LEAR experiment PS187 are presented. Preliminary data for the inclusive production of ..pi../sup +/, K/sup +/, and p from the annihilation of 180 MeV antiprotpns in /sup 28/Si and /sup 238/U are compared with predictions of intranuclear cascade calculations. Proton and pion production data are well reproduced by the calculations, but kaon yields at low momenta appear to be strongly suppressed in the experimental data. 8 refs., 5 figs.
