“…Bellinghausen et al [5] performed an experiment in Bonn in 1985 where the photoproduction of charged pions on 3 He and 3 H was measured in the ∆(1232)-resonance region with an incident photon energy range of 250 to 450 MeV. The results of that measurement for γ+ 3 He → π + +t were compared with the calculation of Sanchez-Gomez and Pascual [6].…”

We have measured the differential cross section for the γ 3 He→ π + t reaction. This reaction was studied using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. Real photons produced with the Hall-B bremsstrahlung tagging system in the energy range from 0.50 to 1.55 GeV were incident on a cryogenic liquid 3 He target. The differential cross sections for the γ 3 He→ π + t reaction were measured as a function of photon-beam energy and pion-scattering angle. Theoretical predictions to date cannot explain the large cross sections except at backward angles, showing that additional components must be added to the model.
