The single-particle character of states outside the doubly magic (radioactive) nucleus {sup 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 {sup 57}Ni , the astrophysically interesting yield for the {sup 56}Ni( p,{gamma}) reaction to the mirror nucleus {sup 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. {copyright} {ital 1998} {ital The American Physical Society}
