Laser induced ionising collisions with cold metastable neon
Modification of the ionising collision rate is demonstrated with cold (~1 mK) metastable neon (Ne*) 3P2 gas in a magneto-optical trap (MOT). A laser tuned close to the 3P2 to 3D3 cooling transition is used as a 'catalysis' to induce collisions between a pairs of trapped metastables. A complex spectrum is observed which demonstrates a dependence on the magnetic sublevels of the transition that the catalysis laser is exciting.
