Protons from the Uppsala University synchrocyclotron have produced positive pions with angular distributions for 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.
