The model of an {alpha} cluster orbiting a closed shell core provides a highly successful description of low lying bound and resonant states of {sup 20}Ne and has been successfully extended to {sup 44}Ti by various authors. This description is closely related to {alpha} scattering from the relevant closed shell core, and although the scattering has previously been reasonably well reproduced with a local optical model potential, few attempts have been made to link the two phenomena. In this paper, a universal {alpha}-core interaction is given which describes the spectra, {ital B}({ital E}2{down_arrow}) transition strengths, {alpha}-decay widths, and differential elastic scattering cross sections for the systems corresponding to {sup 20}Ne={sup 16}O+{alpha} and {sup 44}Ti={sup 40}Ca+{alpha}. This potential has only a single free parameter, the radius, whose value is kept fixed for each nucleus.
