Dewitt et al. derived a useful relation between the plasma screening factor for a reaction of two fusing ions and their chemical potentials, based on the plasma pair distribution functions. We show that their result can be derived in a simpler, more straightforward way, by applying the principle of detailed balance, which also enables us to generalize the relation to reactions involving N fusing ions. In order to demonstrate the usefulness of applying the principle of detailed balance, we calculate the screening factor for the pep reaction, p + e + p -> D-2 + nu(e). For the plasma conditions near the centre of the Sun, the reaction is suppressed by roughly the same amount by which the reaction p + p -> D-2 + e(+) + nu(e) is enhanced. This effect may be measured in the near future.
