We present an experimental and theoretical study of the branching ratios in the dissociative recombination of HD{sup +} with low energy electrons. The results give direct insight into the dynamics of the avoided curve crossing process between the dissociative state and the Rydberg series of the neutral molecule. Excellent agreement between the experimental results and the theory, based on a Landau-Zener formulation of the crossing process, is obtained. {copyright} {ital 1997} {ital The American Physical Society}
