摘要：

The half-lives of very neutron rich isotopes of Ni and Cu have been measured. The isotopes are produced in very asymmetric thermal fission of235U and239Pu at the I.L.L. high flux reactor. They are separated by means of the Lohengrin spectrometer. They are identified with a ΔE-E ionization chamber and implanted in one of the 8 Si planar detectors where the β-particles are also detected. The time correlations between the implantation and the detection of β-particles provide the half-life. The values obtained are compared to current theoretical predictions. © 1990 Springer-Verlag.
