Partial and total autodetachment widths, with interchannel coupling, for the 1Do and 3Do ridge resonances of H−, near the n = 3, 4, 5, 6 and 7 hydrogenic thresholds, have been computed. The Complex Eigenvalue Schrödinger Equations are solved variationally using complex symmetric non-Hermitian matrix equations. The 3Do shape resonance, above the n = 3 hydrogenic threshold, is included in the calculations. An approximate distribution of the vector-coupling configuration mixing coefficients, near the two electron ejection threshold, is obtained. Trends regarding the decay dynamics, the final channel distribution, and the excitation of electrons with large orbital angular momentum, near threshold, are analyzed.
