Orbital alignment effects are investigated for an energy transfer process involving several competing pathways in the system Sr( 5s6p 'P, ) + rare gases and Hz. Most of the cross sections to populate either (I ) the combined 5s6p 'P, and 4d5p 3Fq states or (2) the individual 4d5p 3Fg level show a m

โฆ Synopsis
The effects of orbital alignment on the Ca(4s5p 'P,) to Ca(4sSp'P,) electronic energy transfer process are determined for molecular collision partners, HI, D2, N2, 02, CO, C02, CH,, C2H,, and SF+ Most of the molecules exhibit negligible effects, except for H2 ( D2) and CO*, which show significant preferences for perpendicular and parallel initial orbital alignments, respectively. In the reverse transfer direction, hydrogen exhibits an even larger effect favoring the perpendicular laser polarization.

We have studied orbital alignment effects in a single supersonic jet. The Ar gas behind the nozzle is used as both the collision partner and the carrier gas for free jet expansion. The Ca 4s5p tP l state is prepared by a linearly polarized laser. By varying the angle of the laser polarization with r
The cross section for the process Ca( 4s5p 'P, ) + He+Ca( 4s5p 'P) + He at thermal energies has been calculated as a function of the initial alignment of the Ca(4sSp 'P, ) state. Calculations are in reasonable agreement with experimental data.
