The Quark-Meson-Coupling (QMC) model has been applied to the study of theproperties of even-even super-heavy nuclei with 96 < Z < 110, over a wide rangeof neutron numbers. The aim is to identify the deformed shell gaps at N = 152and N = 162 predicted in macroscopic-microscopic (macro-micro) models, in amodel based on the mean-field Hartree-Fock+BCS approximation. The predictivepower of the model has been tested on proton and neutron spherical shell gapsin light doubly closed (sub)shell nuclei. In the super-heavy region, the groundstate binding energies of 98 < Z < 110 and 146 < N < 160 differ, in themajority of cases, from the measured values by less than 2.5 MeV, with thedeviation decreasing with increasing Z and N. The axial quadrupole deformationparameter, calculated over the range of neutron numbers 138 < N < 184, revealeda prolate-oblate coexistence and shape transition around N = 168, followed byan oblate-spherical transition towards the expected N = 184 shell closure inCm, Cf, Fm and No. The closure is not predicted in Rf, Sg, Hs and Ds as anothershape transition to a highly deformed shape in Sg, Hs and Ds for N > 178appears, while 288Rf (N = 184) remains oblate. The bulk properties predicted byQMC are found to have a limited sensitivity to the deformed shell gaps at N =152 and 162. However, the evolution of the neutron single-particle spectra with0 < beta2 < 0.55 gives unambiguous evidence for the location and size of the N= 152 and 162 gaps as a function of Z and N. In addition, the neutron numberdependence of neutron pairing energies provides supporting evidence forexistence of the energy gaps.
