Thermal neutron capture cross section for the K isomer 177Lum
Abstract
The thermal neutron radiative capture cross section for the K isomeric state in 177Lu has been measured for the first time. Several 177Lum targets have been prepared and irradiated in various neutron fluxes at the Laüe Langevin Institute in Grenoble and at the CEA reactors OSIRIS and ORPHEE in Saclay. The method consists of measuring the 178Lu activity by γ-ray spectroscopy. The values obtained in four different neutron spectra have been used to calculate the resonance integral of the radiative capture cross section for 177Lum. In addition, an indirect method leads to the determination of the 177Lug neutron radiative capture cross section.
