Results on the study of quadrupole collectivity in 54,56,58{Ni} and 52{Fe} using intermediate-energy Coulomb excitation are summarized and discussed in the context of the N=Z=28 doubly-magic shell closure. A complementary experimental approach sensitive to the single-particle structure of exotic nuclei, one-neutron knockout at intermediate beam energies, has been applied to the proton-rich N=16 isotones 34{Ar}, 33{Cl} and 32{S} as well as to 32{Ar} where the knockout residue 31{Ar} is located at the proton drip line. The reduction of single-particle strength compared to USD shell-model calculations is discussed in the framework of correlation effects beyond the effective-interaction theory employed in the shell-model approach.
