A two-range central-plus-tensor potential is assumed for the effective nucleon-nucleon interactions in the shell-model calculation of N=28, 29 and 30 isotopes. A model space of (f<sub>7</sub>2/<sup>n-1</sup>, (<sub>3/2</sub>, p<sub>1</sub>2/, f<sub>5/2</sub>)) is assumed for the proton configuration of N=28 nuclei. The correct isospin wavefunctions proposed by Osnes (1970) are considered. For N=29 and 30 nuclei, the protons are restricted to the 1f<sub>7/2</sub> orbit, and the valence neutrons are allowed to distribute in the 2p<sub>3/2</sub>, 2p<sub>1/2</sub> and 1f<sub>5/2</sub> shells. Energy level spectra for N=28, 29 and 30 nuclei are calculated in a Talmi-type calculation. The calculated results are in good agreement with the experimental observations.
