γ-spectroscopy is an important tool also for nuclear waste transmutation studies. An experiment has been performed at ILL Grenoble to measure [sup 241]Am and [sup 242gs]Am thermal capture cross sections that play a major role for the transmutation of [sup 241]Am in a high thermal neutron flux, coupling γ-spectroscopy with mass spectrometry methods. σ[sub c]([sup 242gs]Am), for which the three main evaluation data libraries were giving very different values, has been measured to be 280±40 barns. That confirms the low cross section value making possible the [sup 241]Am transmutation by thermal neutrons. In the MINI-INCA project, we plan to widen the measurement to other minor actinides of interest using γ and α-spectroscopy of neutron irradiated samples for thermal and epi-thermal fluxes up to 2.10[sup 15] n/s/cm[sup 2]. © 2000 American Institute of Physics.
