You&#x27;re referring to the &#x27;Gamow window&#x27; right? From what I understand, the Gamow window only refers to the energy levels of the particles, rather than temperature per se. I&#x27;m guessing that&#x27;s why approaches like Muon-catalysed fusion can work at lower temperatures.<p><a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Muon-catalyzed_fusion" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Muon-catalyzed_fusion</a>
