Abstract
The very neutron-rich Fe- to Ni-isotopes are of interest since they are located at the very beginning of the astrophysical r-process path. The {beta}-decay half-lives of several isotopes, identified in thermal fission of {sup 235}U or {sup 239}Pu, have been measured at the ILL high-flux reactor using the Lohengrin spectrometer. Half-lives have been determined from time-correlations analysis between the fragment implantation and the detection of the subsequent {beta}-particles in the same detector. With the fragment separator FRS , at GSI, the projectile fragments of {sup 86}Kr have been separated. The {beta}-decay half-life of {sup 65}Fe has been measured.
