Neutron-rich nuclei with magic numbers of neutrons and protons constitute an essential reference to understand and predict the reorganization of shell structure away from the line of beta stability. Knowledge of their structure is furthermore essential for the modelling of regions with even larger N/Z ratios, also relevant in astrophysical modelling. In this work, single-particle states in 79Zn were populated at REX-Isolde, CERN, via the 78Zn(d,p) reaction, in inverse kinematics. The reaction was studied experimentally with the T-REX segmented silicon array and the Miniball array, used respectively for the detection of scattered protons and prompt gamma-rays. The coincident detection of protons and gamma rays is needed to determine the low-lying nuclear structure of 79Zn, the N=51 isotone closest to 78Ni. Preliminary results will be presented. Comparison with state-of-the-art large scale shell model calculations and their relevance to the N=50 region will also be discussed. *** This work was supported by the European Union Seventh Framework Programme through ENSAR, contract no. 262010 and by the project MEC Consolider - Ingenio 2010; CDS2007-00042.
