The [sup 6]Li([alpha],[alpha][prime]) reaction has been studied at [ital E][sub [alpha]]=40 MeV. The angular distribution of the continuum region near the [sup 6]Li[r arrow][alpha]+[ital d] breakup threshold (1.475 MeV) was measured for [theta][sub lab]=10[sup [degree]]--32[sup [degree]]. The data exhibit a lowering in cross section at the forward angle region where the quasifree breakup model calculations fail to explain the data. From the [sup 6]Li([alpha],[alpha][prime]) data at [ital E][sub [alpha]]=50 MeV and the [sup 6]Li([ital p],[ital p][prime]) data at [ital E][sub [ital p]]=65 and 80 MeV we found that the breakup cross section drops below a critical momentum transfer ([similar to]117 MeV/[ital c]). The 40 MeV data reaffirm our earlier finding. The above critical value of the momentum transfer seems to play a crucial role both in the target and projectile breakup reactions and might be useful in determining the onset of the Coulomb dissociation.
