It is shown how branching ratios can be obtained from complex coordinate rotation calculations. The procedure is applied to a rotational Feshbach resonance in a model atom‐diatom van der Waals complex which has two open channels present, and to a simple two‐channel model potential problem which has been treated by other workers.
