Abstract
An extensive on-line nuclear orientation study of the angular distribution in favoured alpha -decay of Bi, At and Rn nuclei near the Z = 82 and N = 12 6 shell closures, performed at ISOLDE is presented. Surprisingly large alph a anisotropies were observed, showing systematic changes from one isotope t o the next. Comparison with various theoretical models proves that anisotro pic alpha -emission in favoured decays of near-spherical nuclei is determin ed by the structure of the decaying nucleus.
