But I think it would require either a transition from D to 3He and then a very slow inverse beta decay, or, alternatively, some kind of neutron capture. This leads one to wonder whether the tritium comes from something else, such as the spallation of a heavier nucleus by way of a fast particle. Another factor pointing in this direction is the observation that tritium is possibly the only radioisotope seen in any significant quantity, whereas other transmutations are generally to stable isotopes.
