An approximately Coulomb-corrected, charge-symmetric 8-matrix prediction for n-H scattering from analyzing p-'He data is described, which deviates at most by 2% from the n-'H total cross section. The total cross section, together with a new measurement of the coherent scattering length now allows two possible sets of singlet and triplet scattering lengths a, and a, . Our analysis agrees well with the new value of the coherent scattering length, and determines the set with a, /a, & 1 to be the correct one.
