Abstract
Heavy neutron-rich nuclei close to N = 126 were produced by fragmentation of a 1A GeV 208Pb beam at the FRS at GSI. The β-decay half-lives of 7 nuclides have been determined using a novel numerical analysis method. The half-lives of 202,199Ir, 200,199Os and 196Re are reported for the first time. The comparison of the data with model calculations provides indications on the importance of first-forbidden transitions on the β-decay of nuclei around N = 126 and Z < 82.
