"An important question is whether or not the observed effect is limited specifically to zirconium vanadium hydride," said Andreas Borgschulte, group leader for hydrogen spectroscopy at Empa. "Our calculations for the material—when excluding the Switendick limit—were able to reproduce the peak, supporting the notion that in vanadium hydride, hydrogen-hydrogen pairs with distances below 2.1 angstroms do occur."
What a (non) surprise. Back in 1989 many articles were published claiming that fusion was impossible because H-H distance cannot be lower than 2.1 A. This is now proven wrong. Though still not enough for fusion to occur, the qualitative limit is broken.
Not saying that I would love a collaboration between the EMPA an ORNL with Holmlid with their technology applied to UDH. But here I guess I'm dreaming.
Note: I was not able to locate the original PNAS article. Apparently the press release has been published before the original article.
