The kinetic-energy distributions are investigated of excited hydrogen and deuterium atoms in states with principal quantum numbers n=3,4,5, and 6, produced in the dissociation of H/sub 2/ and D/sub 2/ molecules by electron impact with energy 90--300 eV. It is shown that the dissociative excitation of the H/sub 2/ and D/sub 2/ molecules results in two groups of atoms, slow and fast. The relative number of the slow and fast atoms depends on the principal quantum number and on the molecule mass. The dependence on the molecule mass points to an important role of the predissociation process in the formation of the group of slow fragments.
