Abstract

Part of the European Institute for Transuranium Elements' research programme which is aimed at elucidating the role of 5f electrons in the chemical bond has been devoted to the study of americium and curium. The investigation of fundamental properties, carried out also in collaboration with foreign research institutes and institutions, has involved: separation and purification of Am and Cm in multigram quantities by combining various separation methods: ion exchange, solvent extraction, extraction chromatography, precipitation; preparation of Am and Cm metals by metallothermic reduction of oxides or thermal dissociation of intermetallics, followed by repeated sublimation for purification purposes; determination of bonding related physical properties: vapour pressures (sublimation enthalpy), electrical resistivity, magnetic susceptibility, volume or crystal structure changes under pressure. Examples of applied research and current work are presented.
