摘要：The rapid proton-capture process (rp-process) produces proton rich nuclei on the surface of
accreting neutron stars. The light curves of type I X-ray bursts are an observable result of the
energy produced. In reaction networks, a series of (p, γ) reactions and β-decays proceed along a
path close to the proton drip-line culminating, for some bursts, in a Sn—Sb—Te cycle. To
address uncertainties in the masses near the proton drip-line, we have observed the β-decay of
neutron-deficient 103,104,105Sb isotopes at the National Superconducting Cyclotron Laboratory at
Michigan State University. A mixed beam of unstable nuclei was produced at the Coupled
Cyclotron Facility and isolated in the A1900 fragment separator. Nuclei were then implanted
and decays were observed in the NSCL β-decay end station. We discuss preliminary results on
β-decay properties and the search for proton radioactivity.
