Sure, it makes sense that it affects the Coulomb barrier (or the Gamow factor&#x2F;window <a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Gamow_window" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Gamow_window</a> ), but doesn&#x27;t muon-catalysed fusion kind of prove that cold fusion could exist? The Wikipedia article suggests that the reactions can take place at room temperature, with the main issue being the reliability of the required reactions.<p>In other words, we already have one proven method for reducing the Coulomb barrier, why is that the only one that&#x27;s possible?
