A detailed quantitative experimental investigation of the influence of nuclear deformation on the angular distribution ofa particles emitted by oriented nuclei is reported. The favored a transitions in the decay of the deformed nuclei 221Fr, 227Pa, and229Pa were studied. In all three cases, very large anisotropies have been observed. The results are in good agreement with calculations based on particle tunneling through a deformed Coulomb barrier. [S0031-9007(99)09374-6]
