A two-trajectory model of thermal Na*-He and Na*-Kr collisions

Investigates the way in which potential curves and interactions can be deduced from measured cross sections for Na*-rare-gas collisions. Using the potential curves computed by Pascale et al. a very simple collision model can be built up on the case of Na*-He collisions: the trajectory effects are due to the short-range part of the potentials, in the region R
