Dissociation of a homonuclear diatomic from an unperturbed electronic state will result in a statistical population of the atomic hyperfine levels. For direct dissociation of $I_{2}(B)$, the $I(^{2}P_{1/2}) F=2$ and $F=3$ levels are expected to show a population ratio of $5/7 (N(F=2)/N(F=3))$. However, an investigation of the hyperfine population distribution on the photolysis energy revealed a strong dependence with population ratios reaching 8/1 with photolysis energies near the $I_{2}(B)$ dissociation limit. It is believed that avoided crossings between the potential energy curves of $I_{2}$ at large internuclear distances are responsible for the non statistical hyperfine population distribution.
