Thanks, Eric, Yes, that fits within my conceptual view of what is possible for hydrogen. I think Stewart has got things a bit muddled. Andy.

On second thought, β- decay isn't correct.  I'm having a hard time saying for sure exactly what kind of beta decay it is.  I don't imagine it's the normal inverse beta decay (inner shell electron capture), since there are probably few inner shell electrons hanging around.  But β+ decay implies positron emission, and I don't see evidence of that.  Wikipedia refers to it as "reversed beta-decay" in one place.  The reaction seems to be:   p + e- → N + v Eric
