Recent statistical multistep analyses of the pre-equilibrium reaction⁹³Nb(p, α) at incident energies of 65 and 100 MeV are reviewed. It is shown that the α-cluster structure of the target nucleus is prominently displayed at the lower incident energy, whereas at the higher value its presence is obscured by the dominance of three-nucleon pickup. This result appears to be simply associated with a difference in the details of the effective momentum mismatch experienced by a cluster knockout mechanism, as opposed to a pickup process.
