Protons from the Uppsala University synchrocyclotron have produced positive pions with angular distributions for(p,&pgr;+),that are quantitatively similar to distributions in the well known deuteron stripping (d, p) reaction. This surprising result, which unexpectedly reinforces the simple view of a proton as a neutron and pion stuck together, comes from the first high‐resolution mesic proton‐capture experiment involving a change in baryon number.
