Abstract

The isotope 178Tl was produced in a bombardment of 102Pd by 78Kr ions at 340 MeV. Reaction products were separated from the beam by the Berkeley Gas-Filled Separator, and implanted into a silicon strip detector where the subsequent α decays were measured. Four distinct α transitions from 178Tl were observed correlated to 6.54 MeV α decays from the previously known 174Au daughter. In some cases, the 174Au decay was followed by a 5.815-MeV α decay. This new transition is tentatively assigned to the decay of the 170Ir ground state. The half-life of 178Tl was measured to be 2549+11ms. The α decay branch of 174Au was determined to be 90(6)%.
