Abstract : A new technique has been used to measure the absolute cross section for the electron transfer reaction, O + Cs to O(-) + Cs(+), for both the triplet P and singlet D states of the oxygen atom. The O atoms are obtained by photodetachment from a .2 to 1.8 keV negative oxygen ion beam using high power pulsed lasers. The cross section for electron transfer with O(triplet P) atoms is of the order of 10 to the -16th sq cm across the energy range studied; and the total cross section for ionization of cesium is less than 30% larger. The electron transfer cross section using O(singlet D) atoms is definitely different only at 1 keV, where the cross section is much smaller than that for O(triplet P) atoms. (Author)
