Talk:psion

J/psi meson
There's been some discussion at w:en:Talk:Psion as to whether psion is the primary meaning of en:J/psi meson, or even whether it's a meaning of psion at all. The alternate name psion has been removed from the J/psi meson article at least once, without discussion. Having been fairly keen on particle physics years ago this has surprised me, but there you are.

Hundreds of attestations of this usage are easily obtained from Google Web or Google Books, see this example for just one. I'm not quite sure whether or how to add this to the article, it might be good to do so to proactively avoid a similar problem at Wiktionary. Andrewa (talk) 05:41, 28 September 2014 (UTC)
