Abstract
Control of the combined Penning and associative ionization cross section is demonstrated with cold (~1mK) metastable Ne (3s3P2) atoms in a magneto-optical trap (MOT). By illuminating the trapped atoms with a near resonant probe laser beam, increased ionization rates are observed at several detunings. The probe beam is swept through a region from +500MHz to -500MHz. The increase in the Penning and associative ionization cross section is observed in both the red and blue regions of the spectrum.
