First access to beta half-lives approaching the r-process path near N=126

T. Kurtukian-Nieto, J. Benlliure, L. Audouin +14

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 beta-decay half-lives of 8 nuclides have been determined. The…
