  Research in atomic and molecular collision processes and spectral line
broadening has been very active since our last report, Peach, Dimitrijevic &
Stancil 2009. Given the large volume of the published literature and the
limited space available, we have attempted to identify work most relevant to
astrophysics. Since our report can not be comprehensive, additional
publications can be found in the databases at the web addresses listed in the
final section. Elastic and inelastic collisions among electrons, atoms, ions,
and molecules are included and charge transfer can be very important in
collisions between heavy particles.
