Abstract
Differential cross section measurements from laser-aligned Mg atoms are compared to theoretical calculations using both time dependent and time-independent formalisms. It is found that both natural and unnatural parity contributions to the calculated cross sections are required to emulate the data when the state is aligned out of the scattering plane.
Highlights
Electron impact ionization processes play an important role in many areas of research, ranging from calculations of stellar and planetary atmospheres through to collision processes in plasmas and in lasers, lighting and Tokomaks
For atomic targets that are in their ground state, a Triple Differential Cross Section (TDCS) is determined, which depends upon the energetics of the collision and the angular distribution of the detected electrons
In this report results are presented for electron-impact ionization of magnesium atoms that are excited and pre-aligned using CW laser radiation at 285.2965nm
