Abstract
Photoparticle spectra from the ,) and ,) reactions have been measured in an angular aperture (FWHM) of 60° centered around 90°, using 28 MeV quasimonochromatic photons from annihilation-in-flight of positrons. The branching ratio for the (γ,) to (γ,) transition amounts to (2.9±1.2)%, while the (γ,) branching to excited states in contributes (24±2)% to the observed (γ,p) cross section.
