Microdistribution of Solar Wind Helium on Itokawa Particle Surfaces
Abstract
We report three-dimensional distribution of solar wind He irradiated on asteroid Itokawa particles with a voxel resolution of 500×800×3 nm3. The distribution is heterogeneous suggesting escape of He by diffusion and mechanical erosion of particle.
