Abstract

In deep inelastic multinucleon transfer reactions of 48Ca +248Cm we observed about 100 residual nuclei with proton numbers between Z =82and Z =100. Among them, there arefive new neutron-deficient isotopes: 216U, 219Np, 223Am, 229Am and 233Bk. As separator for the transfer products we used the velocity filter SHIP of GSI while the isotope identification was performed via the αdecay chains of the nuclei. These first results reveal that multinucleon transfer reactions together with hereapplied fast and sensitive separation and detection techniques are promising for the synthesis of new isotopes in the region of heaviest nuclei.
