Abstract

Angle-integrated cross-section measurements of the ⁵⁶Ni(d,n) and (d,p) stripping reactions have been performed to determine the single-particle strengths of low-lying excited states in the mirror nuclei pair ⁵⁷Cu−⁵⁷Ni situated adjacent to the doubly magic nucleus ⁵⁶Ni. The reactions were studied in inverse kinematics utilizing a beam of radioactive ⁵⁶Ni ions in conjunction with the GRETINA γ-array. Spectroscopic factors are compared with new shell-model calculations using a full pf model space with the GPFX1A Hamiltonian for the isospin-conserving strong interaction plus Coulomb and charge-dependent Hamiltonians. These results were used to set new constraints on the ⁵⁶Ni(p,γ)⁵⁷Cu reaction rate for explosive burning conditions in x-ray bursts, where ⁵⁶Ni represents a key waiting point in the astrophysical rp-process.
