Abstract

The first (d,p) neutron transfer reaction on a neutron-rich r-process nucleus has been measured at the Holifield Radioactive Ion Beam Facility. The ²H(⁸²Ge, p)⁸³Ge reaction was studied by bombarding a 430-μg/cm² (CD₂)_n target with a 330-MeV beam of radioactive ⁸²Ge. The reaction Q value (Q = 1.47 ± 0.02 stat. ±0.07 sys. MeV) has been measured leading to the first determination of the mass of the N = 51 nucleus ⁸³Ge. Excitation energies, angular distributions, and spectroscopic factors for the first two states of ⁸³Ge have also been determined.
