“…Since nucleon resonances have relatively wide widths and are overlapping each other, rich physics observables with a wide angular and energy range are needed to study new resonances. The differential cross sections for the γp → π − ∆ ++ reaction were measured by SLAC at the higher energies of E γ =4, 5, 8, 11, and 16 GeV [13][14][15]. At medium energies, there are only scarce existing data taken by SLAC at 2.8 GeV [16], by CEA for E γ =0.5-1.8…”
