Abstract

The results of a neutron diffraction study on U-1.5Np-0.5O-2 solid solution at low temperature are reported. Below T=12 degrees K the solid solution is magnetically ordered with a magnetic structure different from that of the UO-2 low temperature phase. The temperature dependence of the observed magnetic line width could suggest an eventual short range nature of the magnetic order. The neutron diffraction results are supported by Moessbauer spectroscopy measurements.
