Beta decay rates for nuclei with 115 < A < 140 for r-process   nucleosynthesis
  For r-process nucleosynthesis the beta decay rates for a number of neutron-rich intermediate heavy nuclei are calculated. The model for the beta strength function is able to reproduce the observed half~lives quite well.
