Laser-Induced Charge Transfer Under Crossed-Beam Conditions: Application to the Na + I₂ → Na⁺ + I2− System

Abstract

A crossed-beam charge transfer study was carried out for the Na(3²P_3/2,1/2) + I₂ → Na⁺ + I2− system using laser excitation of the Na atom. The excitation functions were measured for the title reaction, searching for spin orbit effects. A common energy threshold of E₀≃0.23eV was found for both processes. In addition, similar post-threshold laws for each spin-orbit state indicate the absence of such effects over the low collision energy range.
