Phys. Rev. Lett. 86, 4803–4806 (2001)Charge Transfer and Elastic Scattering in Very Slow H++D(1s) Half CollisionsReceived 19 January 2001; published in the issue dated 21 May 2001 Charge transfer and elastic scattering probabilities were measured for half collisions between very slow protons and atomic deuterium. Collision energies down to a few meV, lower by more than an order of magnitude and with better energy resolution than previous measurements, were studied using the dissociation of the HD+ electronic ground state. The collision energy is determined a posteriori from the measured momentum vector of the dissociating charged fragments. The experimental results are in good agreement with our coupled channel calculations. © 2001 The American Physical Society URL:
