Low-energy upbend in the photon strength function of 57Fe
Original language description
In this work, we investigate the photon strength function (PSF) of 57Fe derived from thermal neutron capture on 56Fe, with a focus on the low-energy photon strength below the neutron separation energy. We show that the PSF derived from primary gamma transitions does not support the significant low-energy enhancement previously reported in the Oslo method. The role of secondary gamma transitions and E2 transitions in the total PSF is discussed. Averaging the E2 primary transitions following thermal neutron capture on 56Fe, we obtained an estimate for the E2 strength function for primary gamma transitions in radiative capture, fE2 = 2 x 10-11 MeV-5.
