Abstract
On the basis of features observed in the exact perturbation approach s olution for the eigenspectrum of the dilute A(3) model, we propose exp ressions for excitations in the dilute A(4) and A(6) models. Principal ly, we require that these expressions satisfy the appropriate inversio n relations. We demonstrate that they give the expected E-7 and E-6 ma ss spectra, and universal amplitudes, and agree with numerical express ions for the eigenvalues.
