Abstract

Energy loss and energy straggling of alpha-particles in UO(2) 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 UO(2) layers of 17 different thicknesses. Confirmation of these results was obtained from Rutherford backscattering/channelling experiments with UO(2) 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 UO(2) are briefly treated.
