Atom and molecule emission caused by ion impact into a frozen oxygen target: Role of rovibrational excitation

Translational energy distributions of particles sputtered by 750eV Ne+ ion impact into a cryogenic O2 target are studied using molecular-dynamics simulation. When comparing the energy distribution of emitted molecules to a Thompson distribution, good agreement can only be found for energies E with U
