The structure of unstable nuclei around N = 28 is studied by large-scale shell-model calculations with a new effective interaction including a proper tensor force. The dominance of the tensor force is seen in several observables. The effect appears not only in the single-hole states in K isotopes but also in the occurance of large deformation in {sup 42}Si and in the distribution of the spectroscopic factors for proton pickup from {sup 48}Ca.
