Primer on Collisions
Return to home page


I) Introduction

This primer is based on a couple of talks given by Chun C. Lin to commemerate his winning the 1996 Will Allis prize. In the talks, CCL summarized the work he (and his band of merry men) had done in advancing the field of electron-atom collisions. These talks have been converted into this online primer to provide anyone who is interested in what we do with a fair amount of background material.

The topics choosen for the talks (and this Primer) vary from work done in the 1960's to work that still underway today. Much of the material on helium and neon is provided as a framework for understanding what one should expect in terms of cross sections. The work on pressure effects includes work initially started 35 years ago, but also includes measurements that could not be made until only recently. The work on metastable atoms and the work with atom traps represent the cutting edge of electron-atom collision research.
