Is there anything to this? http://newenergyandfuel.com/http:/newenergyandfuel/com/2007/12/14/a-successful-fusion-process-punches-through-the-coulomb-barrier/ —Preceding unsigned comment added by Vsglobal (talkcontribs) 16:18, 28 April 2009 (UTC)[reply]

Potential

[edit]

there is at least one mistake in the given expression for the potential: a Coulomb-Potential goes with 1/r ! —Preceding unsigned comment added by 134.99.125.193 (talk) 12:35, 23 June 2010 (UTC)[reply]

strong force calculations?

[edit]

I have not studied strong forces, but it seems that, if we are talking about a barrier, we probably want to give examples of calculating that barrier or give some sample pre-calculated values. A calculation presumably needs Coulomb force equations and also strong force equations.

Reference: "To overcome this barrier, nuclei have to collide at high velocities, so their kinetic energies drive them close enough for the strong interaction to take place and bind them together."

If we look only at Coulomb forces, we simply get that the closer the particles are, the greater their repulsion (with "near infinite" force present near zero radius). We need to appeal to strong forces to calculate where the increasing Coulomb repulsion is matched by the strong force in the opposite direction.

I presume learning this force value or this radius value is the whole point of specifying a "Coulomb barrier". Hozelda (talk) 04:12, 26 August 2011 (UTC)[reply]
