✦ Synopsis

Depoharization cross sections for the reaction N~'PJ,,, -+ He( 'Se) + Na2P~'m' + He( 'So) are computed using an impact parameter treatment. Comparison with experimental results is given. The esact calculation is compared to the results of a simplified model where the sodium atom is supposed to be unperturbed for internuclear distanrcs R > 14 au, and the state of ihe quasi molecule is represented by Hund's case b for internuclear distancesR < 14 au. The agreement between exact computation, simplified model, and experimental results shows that even for low velocities the main part of mechanism is Coriolis coupling between r1 molecuhr states.

The quenching cross sections for collision of Cd( 53P, ) with H, or D2 arc measured in the range 430 < T< 900 K. They show a threshold behaviour, increasing by one order of magnitude in the studied temperature range, and a marked isotopic effect, being about two times greater for Hz than for DZ.
