dc.description.abstractVery neutron deficient francium isotopes have been produced in fusion evaporation reactions using 60Ni ions on 141Pr targets. The gas-filled recoil separator RITU was employed to collect the fusion products and to separate them from the scattered beam. The activities were implanted into a position sensitive silicon detector after passing through a gas-counter system. The isotopes were identified using spatial and time correlations between the implants and the decays. Two α-particle activities, with Eα = 7613(15) keV and T1/2 = (15+12 −5 ) ms and Eα = 7684(15) keV and T1/2 = (16+13 −5 ) ms were identified in the new isotope 198Fr. In addition, the half-life and α-particle energy of 199Fr were measured with improved precision. The measured decay properties deduced for 199Fr and 198Fr suggest that there is an onset of ground-state deformation at N = 112 in the Fr isotopes.
