The h92g92 multiplet in Bi210 was populated by Pb208(α,a <FOR VERIFICATION>d) in experiments at 33 and 48 MeV. The strong favoring of the five unnatural-parity states of the multiplet disagrees with one-step transfer distorted-wave Born-approximation predictions. Coupled-reaction-channels calculations explain this effect as interference of direct np transfer and successive stripping amplitudes of comparable magnitude. This holds for weak (low-spin) and strong (high-spin) members of the multiplet.
