Abstract

The single-particle character of states outside the doubly magic (radioactive) nucleus $^{56} Ni$ has been determined through a measurement of the $(d, p)$ neutron transfer reaction using inverse kinematics. From the spectroscopic factors of the low-lying states in $^{57} Ni$ , the astrophysically interesting yield for the $^{56} Ni (p, γ)$ reaction to the mirror nucleus $^{57} Cu$ has been calculated, utilizing charge symmetry. The rate for this reaction in the temperature range typical of novae, supernovae, and x-ray bursts is found to be more than 10 times higher than previously assumed.
