| Abstract: | Mössbauer spectra have been taken of rare earth doped CaSO4 using the151Eu and155Gd transitions. Site assignments have been made to the five principal Gd3+ configurations principally on the basis of point charge calculations. We were unable to distingiush different Eu3+ sites and no conversion of Eu3+ to Eu2+ could be observed after prolonged x-irradiation. |
