Abstract
A new neptunium fluorozirconate glass (NpBa6Zr12Fx) has been prepared and its Mössbauer spectrum was measured at 4.2 K and 77 K. Two resonance lines were observed. One is assigned to the Np4+ ions occupying the normal Np sites in the compound. The other is thought to arise from Np which has replaced some of the Ba2+ ions. The isomer shift of those ions suggests a configuration near 5f4 6d1.The Np4+ ions exhibit paramagnetic relaxationKeywords
