A novel scheme to achieve large-angle atomic diffraction by standing-wave fields is proposed. It uses a high-order Doppleron resonance as a catalyst to speed up a high-order Bragg resonance by orders of magnitude. This effect occurs when the atom–field frequency detuning is such that the Bragg resonance and the Doppleron resonance become degenerate.
