Abstract. It was demonstrated experimentally for the first time that particle growth of photoproduced UF5 was enhanced by ionizing radiation from an α-emitting 241Am source. A gas mixture of UF6, CH4, and Ar in a reaction cell was irradiated with a single shot of a KrF laser at 248 nm to form UF5 particles. Transmission electron microscope images of the samples indicated that the average size of UF5 particles produced without the α-ray source was independent of the laser energy. UF5 particles produced with the α-ray source were found to be much larger in size than those produced without the α-ray source, and the enhancement of particle growth was marked when the laser energy was low. An explanation was attempted for the anomalous behaviors of particle size distribution from the viewpoint of competition between the second-order coagulation rate and the rate of diffusion from the reaction zone.
