The passage around this formula
where and are the alpha-decay and radiative partial widths, their sum, and the resonance energy above the reacting threshold [ 5 ] . The exponential term is why a shift in the resonance’s position has outsized leverage on the reaction rate, and why the disputed radiative-width measurements of the previous section and the sensitivity calculations here are, in the end, two views of the same quantity’s grip on the same exponent.
