Heavy neutron-rich nuclei close to N=126 were produced by fragmentation of a 1 A GeV 208Pb beam at the FRS at GSI. The β-decay half-lives of 8 nuclides have been determined using a novel numerical analysis method. The comparison of the data with model calculations provides indications on the importance of first-forbidden transitions around A=195. The measured data indicate that the matter flow in the r-process to heavier fissioning nuclei may be faster than previously expected.< Réduire
