Coauthored the observation of the <J psi meson> through a narrow peak near $3.1\,\mathrm{GeV}$ in the <invariant mass> of <electron>-<Positron> pairs. The experiment used a precise pair spectrometer to analyze products of <protons> striking a <beryllium> target.<Experimental Observation of a Heavy Particle J by J. J.
