Activation analysis with charged particles

TL;DR: The importance of the minor and trace elements in mineral chemistry is becoming more widely recognized with advances in technology and inter pretation.

TL;DR: The use of nuclear reactions for surface analyses is a field in which a wealth of interesting opportunities exists for small accelerator groups as discussed by the authors, and the field is exciting and interesting both from the scientific standpoint of understanding the fundamental processes involved and from the specific applications which are still being developed.
