Abstract

This contribution reviews the results of recent experiments at the velocity filter SHIP (GSI, Darmstadt) in which a number of very neutron-deficient nuclei with Z=83-88 and N <126 were studied in detail and new nuclides Po-186,Po-187, At-192 and Rn-193,Rn-194 were identified. Complete fusion reactions at beam energies close to the Coulomb barrier were used, followed by particle detection with various detection systems. Peculiarities in a-decay characteristics of the Po186-191 isotopes are discussed in detail. Very recent results for the neutron-deficient At-Ra nuclei from the gas-filled separator RITU (JYFL, Jyvaskyla) are also highlighted.

The application of a new method to reach nuclei in this region - spallation-evaporation reactions of U-238 ions at 1 AGeV on a Be target, followed by the separation with the FRS at GSI is discussed as well.
