The lattice random walk themy of geminate recombination is applied to the low-field behavior of the dissociation probability q of photogenerated charge carrier pairs. It is demonstrated that this theory predicts a zero value of the slope-to-intercept ratio of u(E) for isotropic initial electron dist

## Abstract The recombination of bromine atoms at room temperature has been studied by flash photolysis in the range of 1β100 atm of the inert diluent He, leading to a value for the thirdβorder rate constant of (1.5 Β± 0.2) Γ 10^15^ cm^6^/mol^2^.sec. In the presence of NO the recombination is consid
