We investigate collision dynamics involving two electrons and a quantum dot\nembedded in a quantum wire. One electron is initially at rest in the ground\nstate of the dot, whereas the other electron is incident on the dot with a\nrather well defined velocity. Excitation, reflection and transmission\nprobabilities are obtained by resolving the dynamics explicitly. Also, the\nprobability of both electrons being unbound after collision is studied. It is\nfound that the dynamics is strongly influenced by the presence of doubly\nexcited states; reflection becomes considerably more probable in the energetic\nvicinity of such states. This, in turn, contributes to an increase in the\nprobability of trapping also the second electron within the dot.\n
