The inelastic scattering of fast neutrons from 7Li nuclei was investigated at the nELBE neutron-time-of-flight facility. The photon production cross section of 478 keV γ-rays from the first excited state of 7Li was determined by irradiating a disc of LiF with neutrons of energies ranging from 100 keV to about 10 MeV. The target position was surounded by a setup of 7 LaBr3 scintillation detectors and 7 high-purity germanium detectors to detect the de-excitation γ-rays. A 235U fission chamber was used to determine the incoming neutron flux. The number of detected photons was corrected for the detection efficiency, multiple scattering and the time-of-flight dependent data acquisition dead time. The preliminary results show reasonable agreement with some previous measurments but are about 15 % below the recent data taken at the GELINA facility.

Dynamical Properties

This paper traces the development of the study of the dynamical properties of the semimetallic actinide compounds that have a NaCl crystal structure (monopnictides and monochalcogenides) from the first experiment with a triple-axis spectrometer at Chalk River National Laboratory in 1976. The important realization that the excitations could be overdamped even in an ordered magnetic material, such as UN, because of the interaction between the 5f and conduction electrons remains one of the unique aspects of the physics of these materials. Later experiments on UTe and the transuranium material PuSb are discussed, together with the theoretical concepts that have allowed these results to be understood in terms of the hybridization between the 5f and conduction electrons.
