OK, but can you rule out if he was compensated by Rossi in any way.
Even if he was, what member of the Royal Academy of Science, and Chairman of the Energy Committee would squander their reputation and career for it??
Nope. In fact I can say that he "was" "compensated by Rossi". Rossi paid his travel costs, as he did for the other Swede. But I "really" don't think that that "compensation" qualifies as "being suborned".
