Low energy positron interactions: Cross sections, reaction dynamics, bound states and resonances, applications

 Low energy positron collisions with atoms and molecules have their own intrinsic, fundamental interest, as well as existing and emerging applications in medical and materials sciences.  This talk will provide some brief background to the field, summarise some of the recent important experimental and theoretical advances in positron science, provide examples of the interesting results that have emerged - with many solved and some open problems - and touch on a range of applications of this important field of atomic collision physics.  In particular, a brief focus on the existence, or otherwise, of positron resonances and bound states with atomic and molecular systems will also be provided and the implications of such compound states discussed.

Prof. Stephen Buckman holds B. Sc. and Ph.D. from Flinders University.
Following postdoctoral positions at the University of Manchester and the
University of Colorado, he joined Research School of Physics and
Engineering (RSPE) at the Australian National University (ANU) in 1983.
Prof. Buckman recently retired as the Director of RSPE and is an Emeritus
Professor in ANU since then. He held a Fulbright Senior Fellowship at the
University of California during 2000-2001. He was the Research Director of
the Centre of Excellence for Antimatter-Matter Studies, Australia during
2006-2012. He published more than 210 refereed journal articles and book
chapters.

Prof. Buckman was awarded the Distinguished Alumni Award by Flinders
University (2006), the ANU Vice Chancellor's Award for Distinguished
Service to the University (2008), the Flinders University Convocation
Medal for outstanding achievement of Flinders alumni (2012) and Member of
the Order of Australia for significant service to science in the field of
experimental atomic physics as a leading researcher, academic and author
(2014).
