A novel method for determining absolute chemihuninescence cross sections without knowledge of the absolute detection sensitivity is described for reactions involving eIectronicaUy excited reactants. A study of the Ca(4s4p 3P) + NzO reaction under singie-collkion conditions is presented, and a photon

Cross sections for the quenching of exeted (\mathrm{Ca}{\mathrm{a}}\left(4 \mathrm{~s} \mathrm{p}^{\mathrm{p}} \mathrm{p}{1}\right)) by several gases, determuned drectly by a pulsed lacer fechinque, are compared with those of the analogous ' (P_{1}) states of other group ila and Ifb metal atoms

The cross sections for the deexcitation of He(2 'S), He( 2 'S), and He{ 2 'P) by SiH, and GeH, have been measured and compared with those for the deexcitation by CH,. The major deexcitation processes are ascribed to Penning ionization. The cross sections obtained for He (2 'S) are more than two hund
presented and discussed. Results are also reported showing the variation of the transient negative ion life time within the negative ion resonance for both nuclear-and electron-excited Feshbach resonances.
