Observation of structures at $\sim 17$ and $\sim 38$ MeV/c${}^2$ in the $\gamma \gamma$ invariant mass spectra in pC, dC, and dCu collisions at ${\text{p}}_{lab}$ of a few GeV/c per nucleon

The results of an analysis of the invariant mass spectra of photon pairs produced in dC, pC and dCu interactions at momenta of 2.75, 5.5 and 3.83 GeV/c per nucleon respectively, ar…
