A simple method for the description of the coherent electron emission from two H atoms of the H2 molecule induced by particle impact is suggested. The method is based on a formalism that separates the cross section for the electron emission into an atomic part describing the independent emission from the two H atoms, and a factor giving an account of the interference caused by the coherent emission from the two centres. This separability allows the use of a classical ionization theory to determine the atomic part of the cross section. Calculations applying the classical trajectory Monte Carlo (CTMC) theory have been carried out for 68 MeV amu-1 Kr33+ on H2 collisions. A reasonable agreement has been found between the CTMC results and the recent experimental data obtained by Stolterfoht et al.
