The Gamow factor or Gamow–Sommerfeld factor,[1] named after its discoverer George Gamow,
is a probability factor for two nuclear particles' chance of overcoming the Coulomb barrier in
order to undergo nuclear reactions, for example in nuclear fusion. By classical physics,
there is almost no possibility for protons to fuse by crossing each other's Coulomb barrier
at temperatures commonly observed to cause fusion, such as those found in the sun.
When George Gamow instead applied quantum mechanics to the problem, he found that
there was a significant chance for the fusion due to tunneling.

09-21-2021-1500 - Coulomb barrier
The Coulomb barrier, named after Coulomb's law, which is in turn named after physicist
Charles-Augustin de Coulomb, is the energy barrier due to electrostatic interaction that
two nuclei need to overcome so they can get close enough to undergo a nuclear reaction.
