Abstract
Collision-induced rotational energy transfer of CO(A 1PI) is studied b y two-color double resonance multiphotoionization spectroscopy. With H e as a collision partner, the cross sections for CO(A 1PI, v=3) from J =2, M=2, e to J'=1, .M'=1, e and J'=1, M'=-1, e, are 162+0.32 and 0.89 +0.18 angstrom2 respectively. The corresponding values for CO-Ar are 3.13+0.62 and 1.24+0.24 angstrom2. Two sums of symmetry changing cross sections are also obtained, the ratios of which are in good agreement with those predicted by a quantum scattering formulation of Alexander and Davis.
