    The effects of electron beam irradiation on Pr24O44 were followed at high resolution in a JEM-4000EX electron microscope. Two categories of electron beam effects are reported. In one image sequence, the orientational transformation of Pr24O44 from the [100] to the [313] direction was observed to occur. In another sequence, reduction of Pr24O44 to Pr40O72 resulted from intense beam irradiation. Electron diffraction patterns showed the further reduction of the specimen to Pr7O12 and finally to Pr2O3.
