Gamow barrier
WebMar 7, 2011 · George Gamow in 1928, just two years after the invention of quantum mechanics, proposed that the process involves tunneling of an alpha particle through a large barrier. The barrier is created by the Coulomb repulsion between the alpha particle and the rest of the positively charged nucleus, in addition to breaking the strong nuclear forces ... WebGamow made the following assumptions: An alpha particle may exist as an alpha particle heavy nucleus. An alpha particle is in constant motion and is held in the nucleus by a potential barrier. The alpha particle may tunnel …
