A narrow resonance not too far from the Gamow peak may supplant the latter (see Fig. 2.11). The reaction rate coefficient is then given in analogy to Eq. (2.53) by... 

Show that the integration procedure over the Gamow peak implies for that peak a 1/e full width of A = (4/ /3)-s/(E0kT),le. essentially twice the geometric mean of Eo and kT. 

Gamow factor, which increases with increasing energy. The product of these two terms produces a peak in the overlap region of these two functions called the Gamow peak (Fig. 12.9). This peak occurs at an energy E0 = (bkT/2)2 3. 

A consequence of the steepness of both functions defining the Gamow-peak is an extreme sensitivity of the Maxwellian-averaged cross section to temperature ...
