Abstract

Full close coupling calculations of magnetic transitions in He + H 2 collisions are reported. The results are analyzed using the uncoupled space frame approach of Kouri and Shimoni. This enables one to study the magnetic transition T-matrices as a function of orbital angular momentum quantum number l. The results for transitions which are elastic in rotor state j are found to be dominated by j z -conserving transitions. Those which are inelastic in j are dominated by j z -conserving transitions for very low l but at higher l values, the non- j z -conserving transitions dominate. The results for He + H 2 are consistent with the recent studies of Shimoni and Kouri of the coupled states approximation.
