Abstract
We have determined the internal-state distribution for the HD product of the reaction of gas-phase D atoms with H atoms chemisorbed on Cu(111). The populations of the vibrational states , 1, 2, and 3 are comparable, while that for is considerably smaller, giving a mean vibrational energy of eV. The mean rotational energy falls with increasing , from eV for to eV for , with an overall mean rotational energy of eV. The maximum internal energy observed is eV, consistent with the total energy available to the product. Results are compared with recent calculations.
