Division B Commission 14 Working Group: Collision Processes

Abstract

Since our last report (Peach & Dimitrijević 2012), a large number of new publications on the results of research in atomic and molecular collision processes and spectral line broadening have been published. Due to the limited space available, we have only included work of importance for astrophysics. Additional relevant papers, not included in this report, can be found in the databases at the web addresses provided in Section 6. Elastic and inelastic collisions between electrons, atoms, ions, and molecules are included, as well as charge transfer in collisions between heavy particles which can be very important.

Databases for collisional and radiative processes in small molecules needed for spectroscopy use in astrophysics

“…Comprehensive and up-to-date reviews on electron scattering data have been triennially realised by the IAU Division XII, Commission 14 working group: Atomic collisions (Peach et al, 2009;Peach & Dimitrijević, 2012;Peach et al, 2015). Data covered by BEAMDB for triatomic molecules include H 2 O, H 2 S and N 2 O.…”
