Abstract

Recent calculations suggest that, at late times in the r-process, the rate of neutron capture by ¹³⁰Sn has a significant impact on nucleosynthesis. Direct capture into low-lying bound states is likely the dominant reaction in the r-process near the N=82 closed shell, so reaction rates are strongly impacted by the properties of neutron single particle states in this region. In order to investigate these properties, we have acquired (d,p) reaction data in the A∼132 region in inverse kinematics using ∼630 MeV beams (4.85 MeV/u for ¹³⁰Sn) and CD₂ targets. An array of Si strip detectors, including SIDAR and an early implementation of the new Oak Ridge Rutgers University Barrel Array (ORRUBA), was used to detect reaction products. Preliminary results for the ¹³⁰Sn(d,p)¹³¹Sn experiment are reported.
