Outline of Final Research Achievements

One might expect that when an electron collides with a molecule, the probability of occurring a collision and the physical content of the collision must be largely dependent upon the angle between the incident electron beam axis and the molecular axis as well as upon the impact parameter. The objective of this project has been to open up a new research area to investigate such stereodynamics of electron-molecule collision. For this purpose, a new experimental technique, which measures the differential cross section of electron scattering as a function of spatial orientation of the target molecule and momentum transfer, has been developed. As a result, this project has successfully and for the first time found effects of stereodynamics on the cross section, which is much more substantial than supposed.
