Half-life (T1/2) and β-delayed neutron branching (Pn) values of 492(25) ms and 49(8)%, 350(15) ms and 72(8)%, and 93(13) ms and 90(10)% for the r-process nuclei 137,138,139Sb, respectively, have been measured at the CERN On-Line Isotope Mass Separator (ISOLDE) facility by counting β-delayed neutrons. More precise T1/2 and Pn values of 300(15) ms and 27(4)%, and 273(7) ms and 50(8)% for 136,137Sn, respectively, have also been measured. The sources were prepared by using the selective ionization of Sb or Sn with the Resonance Ionization Laser Ion Source and the high-resolution mass separator. The new data for Sb isotopes are compared with calculated T1/2 and Pn values for both spherical and nonspherical shapes. The data have been incorporated into parametrized nucleosynthesis calculations of the r process in high-entropy winds of core-collapse supernovae in order to study the properties of the A = 130 solar-system r-process abundance peak.
