Abstract: Experiments on ion implantation were performed in order to better characterize diffusion of noble gases in lunar soil. 4He+ at 50 keV with 5×1016 ions/cm2 was implanted into lunar simulants and crystal ilmenite. Helium in the samples was released by stepwise heating experiments. Based on the data, we calculated the helium diffusion coefficient and activation energy. Lunar simulants display similar 4He release patterns in curve shape as lunar soil, but release temperatures are a little lower. This is probably a consequence of long-term diffusion after implantation in lunar soil grains. Variation of activation energy was identified in the Arrhenius plots of lunar simulants and Panzhihua (攀枝花) ilmenite...
