Direct evidence for an inelastic neutron acceleration process on 177mLu(n,n’) reaction
O. Roig et al (A. Letourneau, D. Dore, Ch. Veyssiere)
The inelastic neutron acceleration (INNA) cross section on the long-lived metastable state of 177Lu has been measured from a new isomeric target using a direct method. High energy neutrons have been detected using a specially designed setup and a cold neutron beam extracted from the ORPHEE reactor facility in Saclay. The results confirm the high cross section value previously published for INNA cross section on the 177mLu.
