Query: Transmission coefficients in compound-nucleus reaction theory   A recent article (D.A. Brown, et al., Phys. Rev. C98 024616 (2018)) rproposed
a modification of the cross section formula used in practical calculations of
compound nucleus reactions. We discuss the main concepts and approximations of
statistical reaction theory and conclude that the standard practical
implementations of the cross section formula remain the preferred choice.
