Abstract

The reaction127I(n, γ)128I has been investigated at the tangential facility of the McMaster University Nuclear Reactor using a pair spectrometer. A total of 248 transitions were observed in the photon energy range 4.5–6.8 MeV. Below an excitation energy of 1 MeV more than 50 levels have been inferred. Through use of 28 levels with well established energies, a neutron separation energy of 6826.12±0.05 keV was determined. The level density up to an excitation of 2.5 MeV was examined on the basis of a statistical model and found to agree with current parameter values. TheE1 andM1 strength functions were determined and the influence of the giant dipole resonance on the former investigated.
