Abstract
Relative yields of capture photons have been observed for four nuclei at angles of 55°, 90°, and 125° in bombardments with 14-MeV neutrons. The yields from , , and show smaller fore-aft anisotropies than those observed in corresponding proton captures. This suggests that the forward peaking in () reactions is due mainly to direct rather than collective capture amplitudes. Photons from peak backward, but this peaking cannot be straightforwardly accounted for in terms of the interference between the collective excitations dominant in this energy region.
