Lab-energy distributions of HD$sup +$ ions formed in the D$sup +$(H$sub 2$,H)HD$sup +$ reaction were measured with high resolution for collisions with relative energy W in the range 1 eV less than or equal to W less than or equal to 5 eV. In addition to observing the transition from long- to short-lived collision complexes and the relative growth of repulsive interactions, one also observed the possible participation of charge transfer in the entrance channel of the reaction. The charge transfer contribution was suggested by independent study of the H$sub 2$$sup +$(D,H)HD$sup +$ reaction, which follows predominantly direct interactions over the range 0.1 eV less than or equal to W less than or equal to 10 eV. HD$sup +$ ions formed in the H$sub 2$$sup +$(D,H)HD$sup +$ reaction have recoil energies in the same range as HD$sup +$ ions which appear as a distinct shoulder in the D$sup +$(H$sub 2$,H)HD$sup +$ product distributions. For W greater than or equal to 8 eV, the H$sub 2$$sup +$(D,H)HD$sup +$ reaction yields a small fraction of H atoms which may be in an electronically excited state.
