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