The Nucleus Resolved, Ch Fusion: the cross section computed and the power balance made honest

Problem

\rho R = 2.0\,\mathrm{g\,cm^{-2}}

. Using the burn-fraction model

f_b = \rho R/(\rho R + H_B)

with

H_B = 7\,\mathrm{g\,cm^{-2}}

, calculate the fraction of the deuterium-tritium fuel burned.
