heal.abstract	By applying a theory which unifies the ab initio treatment of electronic structure, of electron correlation and of valence-Rydberg-continuum interactions, we calculated hitherto unknown properties of the Al2Fo spectrum. The KL(3s3p)3Po nd states lie above threshold, starting with the 3d state at 3.0 eV. They decay by autoionization with rates of the order of 1012 s-1. The higher-lying autoionizing (3s3p)1Pond states exhibit a stronger interaction with the 3s2nf, εf channel, resulting in an increase of the small quantum defect of the Rydberg series from its Hartree-Fock value by a factor of 20. Using a correlated wavefunction for the2D lowest state, the oscillator strengths for2D-2Fo transitions for low n, for high n and for free-electron energies up to 2.7 eV are computed.	en
