Use of polarization techniques to investigate the dynamics of Penning ionization reactions

· Phys. Rev. A; (United States)
A new technique is used to probe the dynamics of Penning ionization reactions involving He(2/sup 3/S) atoms and the targets K, Rb, Cs, O/sub 2/, Cl/sub 2/, and CF/sub 3/Cl. In this technique, the electrons on the 2/sup 3/S atoms are spin labeled and the polarization of the Penning electrons is determined. The data indicate that, for Rb, a significant fraction of the ionization occurs through energy transfer to a core excited state followed by autoionization. The data for the molecular targets confirm that ionization via ionic channels is important.
