With a relatively simple trial wave function, nontrivial variational bounds are obtained on some transition amplitudes for the —charge-exchange reaction in the impact-parameter model for -H scattering. Preliminary results imply that the two-state traveling molecular expansion is superior to the two-state traveling atomic expansion below 25 keV, that the Euler-Lagrange variational method is not necessarily superior to the static method, and that neither is the "best variational method."
