The ionization efficiency under fast atom bombardment conditions with liquid matrix have been studied. The dependence of fast atoms, Xe, Ar, and He, for the ionization efficiency from the surface of matrix solution bombarded with 6 keV atom beams has been rationalized from the standpoint of elastic/inelastic collisions between a fast atom and a matrix molecule in the surface layer. A relationship between ionization efficiency and atomic mass, which was formulated by a collision theory, predicted a tendency that the efficiency approaches asymptotically to a finite value with increasing atomic mass. The curves for the ionization efficiency versus atomic mass, obtained by using a few compounds, were in agreement with the theoretical prediction in the tendency.
