We reexamine our earlier treatment of favored alpha decays and find that the predicted half-lives are insensitive to the precise geometric form of the nuclear potential. We seek to constrain this potential more tightly by requiring it, in addition, to describe simultaneously the low-lying positive parity spectrum of {sup 212}Po, the {ital E}2 and {alpha}-decay rates of these states, and the differential cross sections for low-energy elastic {alpha} scattering from {sup 208}Pb. A recently proposed parametrization of the {alpha}-core potential is capable of achieving this goal and, although some ambiguity remains in the choice of parameters, the proposed potential describes all the data well and supports the assignment of {ital J}{sub {ital I}}{sup {pi}}=18{sup +} to the 45.1 s isomer at 2.922 MeV in {sup 212}Po. {copyright} {ital 1996 The American Physical Society.}
