Laser Preparation and Probing of Initial and Final Angular Momentum States in the Collision-Induced Energy Transfer Ca (4s4p 3P1) + He → Ca (4s4p 3P2) + He

Abstract

The nature of atomic collisions can be revealed through the preparation and probing of aligned or oriented states. Intense interest in this research topic is evident by the numerous current experimental and theoretical investigations.1 The results of these studies provide a means of visualizing the important mechanisms and symmetries of the collision process with unprecedented detail.
