Collisions of Positrons and Positronium
with Atoms and Molecules

címmel előadást tart.

Az előadás előtt 10:30-tól tea.
Vendégeket szívesen látunk.

Máté Zoltán

Recent progress in the study of positrons and positronium colliding with
atoms and molecules will be discussed. The focus will be on experimental
techniques and results, which comprise both integral and differential
cross-sections [e.g. 1-5]. Measurements for positronium formation and
direct ionization by positron impact now include cross-sections for Ps
formation in an excited state [6] and/or excitation of the residual ion
[7]. Data (integral and differential) on the scattering and fragmentation
of positronium [8, 9] will also be presented. Comparisons with theories
and other projectiles will be made where possible and future prospects
will be considered.
