Kinetic Processes in High Pressure Gases: Excited State Collisions.
Abstract
A nitrogen-pumped dye laser system has been used to investigate the 3(2P) yields n(2)D(3/2), (5/2) and 3(2P)(1/2), 3-2 yields n(2)S(1/2) (6 < or = n < or = 22) line profiles for sodium perturbed by .2 to 2 Amagats of argon. Sodium was ionized in a stepwise process which incorporated one of the above resonant transitions as an intermediate step. The relative ion yield was determined as a function of laser wavelength and the resulting data analyzed to obtain absorption profiles and line shifts for nd, ns yields 3p transitions. We report the total Penning ionization cross sections for He(2(3)S(1)) atoms incident on Cd and Zn. The measurements are made for relative collision velocities above thermal by using a beam. Previous metal vapor studies of Cd and Zn have been confined to thermal velocities in pulsed after-glow experiments. We also report the observation of HgBr(B-X) fluorescence resulting from collisions of HgBr2 with a vibrationally excited beam of nitrogen molecules in the A(3) sigma (+) (mu) electronic state.
