Calculation of Molecule-cluster Collision Cross Sections

Abstract

A model is developed for calculating molecule-cluster collision cross sections in homogeneous and ion-induced cluster formation. The model is applied to investigate the dependence of the molecule-cluster collision cross section of ammonia, water, argon, methanol, and methyl chloride on temperature, cluster size, and cluster charge. The calculation results show that the collision cross section is increased by the cluster charge only for clusters of the size less than about 100.
