Abstract
In briefly annealed silicon samples implanted with hydrogen and deuterium an electron paramagnetic resonance spectrum is detected. It is identified as arising from a hydrogen molecule oriented in the 〈111〉 crystallographic direction and located most probably at an interstitial site. Such a result is consistent with recent theoretical calculations predicting such an orientation to be of lowest energy. In addition, evidence is obtained indicating that the hydrogen molecule forms a part of a more elaborate hydrogen cluster.
