Extensive \alpha -decay studies of the very neutron deficient isotopes 191Po, 195Rn, and 196Rn have been performed at the RITU gas-filled recoil separator. The recoil-\alpha --(\alpha ) correlation technique and the \alpha --\gamma  coincidence technique have been utilized to unambiguously connect the observed \alpha -decays to proper nuclei. Illustrative examples on how the \alpha -decay can yield spectroscopic information on the nuclei studied will be presented.
