      abstract     = {Inelastic proton scattering of 70,72,74Ni and 76,78,80Zn
                      was performed at the RIBF facility of the RIKEN Nishina
                      Center, Japan, as part of the first SEASTAR campaign.
                      Radioactive isotopes were produced by the in-flight fission
                      of a beam of 238U ions incident on a 3 mm thick Beryllium
                      target. After production, neutron-rich radioactive isotopes
                      were selected and identified on an event-by-event basis
                      using the BigRIPS separator. Selected isotopes of interest
                      were focused onto the liquid hydrogen target of the MINOS
                      device and gamma-rays from inelastic (p, p') reactions were
                      detected with the DALI2 array, consisting of 186 NaI
                      crystals. Outgoing beam-like particles were identified using
                      the ZeroDegree spectrometer. Gamma-rays produced in the
                      reaction were Doppler corrected and the first 2+ and 4+
                      states in all the isotopes were identified. Detailed data
                      analysis was performed including the implementation of
                      algorithms that discriminate events where more than one
                      particle was present. Using detailed Geant4 simulations,
                      exclusive cross-sections for inelastic proton scattering
                      were obtained. Deformation lengths were deduced from the
                      experimental cross-sections using the coupled-channel
                      calculation code ECIS-97. The deformations lengths of
                      72,74Ni and 76,80Zn were found to be fairly constant at a
                      value of 0.8(2) fm, suggesting similar vibrational
                      amplitudes, while the isomeric presence in the secondary
                      beams of 70Ni and 78Zn allowed only lower limits for those
                      two isotopes. By combining the deformation lengths with the
                      known B(E2; 0+ -> 2+) values, the neutron-to-proton matrix
                      element ratios, Mn/Mp, were obtained. A clear indication of
                      the closed proton shell in the 72,74Ni could be observed, as
                      Mn/Mp > N/Z, indicating an increased contribution of the
                      neutrons to the vibrational amplitude. For the case of
                      76,80Zn, Mn/Mp < N/Z, indicating an open proton shell.},
