Might be a starting point if you have more time to read than i do, though! EDIT Hmm [1]: &amp;gt; Interestingly, the existence of a nuclear excited state of such low energy seems to be a coincidence and there is currently no conclusive theoretical calculation that allows to predict nuclear levels to this precision. And there is a paper with a ton of detail and some nice diagrams of energy levels [2], but i&amp;#x27;m not sure it really gets at &amp;quot;why&amp;quot;.
