[en] The α+core structure is investigated in the nuclei ⁹⁰Sr and ⁹⁸Pd. The ground state bands of the α+⁸⁶Kr and α+⁹⁴Ru systems were calculated with a local cluster-core potential, where only the radial parameter is variable. The calculated spectra give a good general description of the experimental ⁹⁰Sr and ⁹⁸Pd levels. The reduced α-widths, B(E2) transition rates and rms intercluster separations are determined for the ground state bands of the two nuclei. The calculations reproduce correctly the order of magnitude of the experimental B(E2) values of ⁹⁰Sr without the use of effective charges and indicate that the first members of the ground state band of ⁹⁸Pd present a stronger α-cluster character. Predictions concerning a negative parity band of the α+⁹⁴Ru system are also shown.
