Actually, I believe my definition is misleading because I actually defined “aneutronic fusion reaction” rather than “aneutronic fusion”. Perhaps this is a better definition:
aneutronic fusion – Fusion in which no neutrons are produced [em]in the primary reaction[/em].
That is, there are aneutronic fusion reactions in which no neutrons are produced, but there are also side reactions (which comprise less than 1% of the total fusion reactions) in which neutrons are produced.
