The neutron orbits $$g_{9/2}$$, d$$_{5/2}$$ and s$$_{1/2}$$ are assumed to be responsible for the swift onset of collectivity observed in the region below $$^{68}$$Ni. In order to gather information on the single-particle energies and spectroscopic factors of these orbitals, single-particle states in the nucleus $$^{67}$$Ni were populated using the reaction $$^{66}$$Ni(d,p), in inverse kinematics, at REX-ISOLDE, CERN. The new isotope was studied using combined particle-$$gamma$$ spectroscopy. Comparison with DWBA calculations, permitted the identification of positive parity states with a substantial amount of $$nu$$d$$_{9/2}$$ (1007 keV) and $$nu$$d$$_{5/2}$$ (2207 and 3277 keV) single-particle strength. Comparisons with extended Shell-Model calculations was also performed to confirm the single-particle nature of these states, and to deduce general properties around $$^{68}$$Ni.
