Research Abstract

We demonstrate that the ^<241>Am-Pd alloy produced by the coupling reduction process of AmO_2 and Pd powder brings a high resolution ^<237>Np Mossbauer spectrum. We built up the ^<237>Np Mossbauer spectroscopy system for applying solid state physics of the transuranium compounds and the nuclear fuels.
