nuclei created electronuclear gravity.
What ever word you add to gravity its just nonsense! Fusion is a complex process that involves different layers of action as the nuclear structure is formed in steps. The classic idea of a nuclear force was refuted (falsified) quite a long time ago. If two Deuterium touch at rest nothing will happen. If they touch spin aligned then D*-D* may come into live where in the case of D*-D* this can be several steps to more stronger electro weak D***-D*** bonds. Where the exact starting point of the D-D meta stable state occurs is an other discussion.
So as Göthe ones said in Faust: If you don't understand it invent a new word...
