PHYS 7141 Atomic Collision Processes
A/Prof Igor Bray and Dr. Dmitry Fursa
Level: Fourth year
Duration: 8 weeks in first semester
Class Contact: Two 75-minute lectures per week

The 1990s have seen immense progress in the field of atomic
collisions. Interactions between electrons, positrons, photons and
atoms, which have many scientific and industrial applications, may now
be calculated to often a high accuracy. Much of this progress is due
to the work that originated here at Flinders. The course will begin
with an introduction to scattering theory concepts, and build on to
formal scattering theory. The recently developed numerical methods
will be discussed with some examples of experimental techniques given.
