Range, Energy Loss, Energy Straggling and Damage Production for Alpha-Particles in Uranium Dioxide.

Energy loss and stragglign of alpha-particles in UO2 were measured for alpha-energies up to 8.78 MeV. Alpha-sources of Pu-239 and a "multienergy source" emitting alpha-particles of five different energies obtained by recoil implantation from a Th-228 source were coated with UO2 layers of 17 different thicknesses. Confirmation of these results was obtained from RBS/channeling experiments with UO2 single crystals preimplanted with He-ions. The measured energy loss values were used to deduce the range-energy relation. The results are in good agreement with calculations using the code TRIM 96. The energy straggling results are discussed in the frame of Bohr's theory. Finally, defects and damage produced by alpha-particles and He-ions in UO2 are briefly treated.
