Cross sections for the alkali atom-Cl2 reactions

Abstract
Total reaction cross sections for the alkali atoms with chlorine molecules have been obtained by direct measurement of alkali atom transient decay rates. The results are Na, 124 Å2; K, 154 Å2; Rb, 190Å2; and Cs, 196 Å2. These results are accurate to about 15%. The relative accuracy within the alkali atom sequence is about 5%. The results are compared with theoretical calculations.
