Total and triple differential cross sections for the ionization of these targets were calculated in the distorted wave Born approximation using Gaussian molecular orbitals. Different models were tested. The obtained theoretical results reproduced, in most cases, the features observed in the experimental data.enAtomic, molecular and optical physicsPhysical sciencesIonization of molecules by positron and electron impactDistorted-wave Born approximationTotal and triple differential cross sectionsArticle
