Beta-decay properties of the neutron-rich ^94-99Kr and ^142-147Xe isotopes

Summary, in English

Beta-decay half-lives and delayed-neutron emission probabilities of the neutron-rich noble-gas isotopes ^94-99Kr and ^142-147Xe have been measured at the PSB-ISOLDE facility at CERN. The results are compared to QRPA shell-model predictions and are used in dynamic calculations of r-process abundances of Kr and Xe isotopes.
