Abstract
The31P(γ, xn) cross section was measured from threshold up to 25 MeV, using the bremsstrahlung photon beam from the 35 MeV linac. Several analysis procedures were used to compute the photoneutron cross section from the experimental yield curve. Our results are compared with other bremsstrahlung measurements and with the quasimonoenergetic photon work by the Saclay group. The leading edge of the giant resonance shows an extremely rich fine structure which seems to be characteristic for nuclei in the 1d-2s shell.
