THE THRESHOLD ANOMALY - AN EXPERIMENTAL OVERVIEW

Research output: Contribution to journalLiterature reviewpeer-review

Abstract

The term threshold anomaly describes the rapid localised variation in the strength of the nuclear potential exhibited in low-energy heavy ion scattering. The experimental evidence for the anomaly in different heavy ion systems is reviewed and discussed in terms of a dispersion relation in the nuclear optical potential. Evidence is presented for the occurrence of an anomaly in non-elastic scattering processes and new areas where the phenomenon might be found are discussed. The link between the threshold anomaly and sub-barrier fusion enhancements is discussed.
