摘要：

A quantitative analysis of the influence of small-angle multiple scattering on fast molecules dissociating in solids is made using a Monte Carlo technique. Simulations allow the computation of asymptotic velocities of all of the fragments after Coulomb explosion. It is found that only the simultaneous treatment of the Coulomb explosion and the multiple scattering leads to satisfactory agreement of the simulations with experimental data. Limits on the range of validity for Coulomb-explosion-imaging experiments are determined. It is shown that these limits are ample to allow quantitative spectroscopic data to be extracted from such experiments.
