\ensuremathα-nucleus potentials are one important ingredient for the understanding of the nucleosynthesis of heavy neutron-deficient p nuclei in the astrophysical \ensuremathγ process where these p nuclei are produced by a series of (\ensuremathγ,n), (\ensuremathγ,p), and (\ensuremathγ,\ensuremathα) reactions. I present an improved \ensuremathα-nucleus potential at the astrophysically relevant sub-Coulomb energies which is derived from the analysis of \ensuremathα decay data and from a previously established systematic behavior of double-folding potentials.
