Talk:hyperhydrogen

Possibly the definition should be one of more neutrons; the hyperhydrogen isotopes that I've found documentation of are lambda H-3 (pnΛ), lambda H-4 (pnnΛ) and lambda H-6 (pnnnnΛ) - look also for lambda H-8 and double lambda H-4 (pnΛΛ). 80.176.90.190 22:41, 28 November 2017 (UTC)
