Abstract
The effect of shell model configuration mixing on the reduced α-amplitude in heavy nuclei is investigated and discussed with respect to the question of α-clustering in nuclei. It is shown that extensive configuration mixing may enhance the α-amplitude under the Coulomb barrier by huge, largely arbitrary factors. In contrast to this the actual αclustering in the nuclear surface may well be described within the shell model including only relatively few configurations in the open shell.
