Lncs 651 - an introduction to halo nuclei

An Introduction to Halo Nuclei Department of Physics, University of Surrey, Guildford, GU2 7XH, UK Abstract. This lecture will not aim to provide an exhaustive review of the field ofhalo nuclei, but rather will outline some of the theoretical techniques that have beenused and developed, both in structure and reaction studies, over the past decade tounderstand their properties. A number of review articles have recently appeared inthe literature [1–10] which the interested reader can then go to armed with a basicunderstanding of how the theoretical results were produced.
