Graphic has wrong formula

In the graphic, the tunneling probability throught the coulomb barrier is given as 'exp(√E_G/E)', which is a function that *falls* with increasing energy E. The proper formula would be 'exp(-√E_G/E) = exp(√E/E_G)'. — Preceding unsigned comment added by ~2025-34447-34 (talk) 23:26, 17 November 2025 (UTC)

Temperature dependence

This statement:

"for any given temperature, the particles that actually fuse are mostly in a (temperature-dependent) narrow range of energies known as the Gamow window".

... does not indicate the direction in which the Gamow window is temperature dependent. It would be nice to summarize by saying something like "The width of this window increases in a non-linear manner with temperature," or some such.

It is Δ(T) = 4(k_BT·E_max/3)^1/2 in joule, E_max^1/2 = E_G^1/6(k_BT/2)^1/3 with Gamow's peak at E_max(T) in joule;

thus Δ(T) = 4/3^1/2/2^1/3•E_G^1/6(k_BT)^5/6.

Double log. graphs:

2 ln (Δ(T)/4) = ln(k_BT) + ln (E_max(T)/3) and 6 ln (Δ(T)/4) = 5 ln(k_BT) + ln(E_G) - 3 ln(3) - 2 ln(2).

Needs more content

The article needs an actual quantitative presentation of the equation.--75.83.76.23 (talk) 14:26, 12 August 2013 (UTC)

thus Gamow window Δ(T) = 4/3^1/2/2^1/3•[E_G(k_BT)⁵]^1/6 in joule and ln (Δ(T)/4) = [5 ln(k_BT) + ln(E_G) - 3 ln(3) - 2 ln(2)]/ 6,

where E_G Gamow's energy in joule.

Merge S-factor into this article?

The article S-factor is a stub that just defines S and links to this article. Since this article already defines several quantities that are related to the Gamow factor, such as the Gamow energy and the Sommerfeld parameter, it seems it would be simple and useful to also define the S-factor here, in which case we wolud no longer need that article.

I have nothing AGAINST this idea.--ReyHahn (talk) 18:48, 16 December 2025 (UTC)
