Popis:	This study measured the absolute ion desorption yield from the surface of solid Ne and Ar by low-energy Neq+ (q = 1–4), Arq+ (q = 1–6), and Krq+ (q = 2–6) ion impacts. Results revealed the dependence of ion desorption yield on the potential and the kinetic energies of the incident ions, as well as its linear proportionality with the former. Present results could not be explained by existing models for ion desorption from insulator surfaces. We proposed a new mechanism of ion desorption that considers the contribution of both energy types to ion desorption.This study measured the absolute ion desorption yield from the surface of solid Ne and Ar by low-energy Neq+ (q = 1–4), Arq+ (q = 1–6), and Krq+ (q = 2–6) ion impacts.
