The mechanism for ((d,)) reactions is discussed, with special attention given to the Mo98(d,)Nb96 reaction leading to the presumed [(g92)p(d52)-1n] multiplet in Nb96. The analysis relies on the coupled-reaction-channel approach for including contributions from the successive pickup processes (d,t)-(t,) and (d,He3)-(He3,). An excellent description of both the shape and magnitude of the available data is possible with adjustment of only a single parameter, namely the effective strength D0 of the direct plus nonorthogonality terms in the reaction amplitude. The effective direct term dominates for low-spin final states of unnatural parity, while the (d,t)-(t,) term dominates for high-spin final states of natural parity. Extension of the results to the Mo92(d,)Nb90 reaction is also discussed.
