We have calculated the ground-state energy of the doubly magic nuclei {sup 4}He, {sup 16}O, and {sup 40}Ca within the framework of the Goldstone expansion starting from various modern nucleon-nucleon potentials. The short-range repulsion of these potentials has been renormalized by constructing a low-momentum potential V{sub low-k}. We have studied the connection between the cutoff momentum {lambda} and the size of the harmonic oscillator space employed in the calculations. We have found a fast convergence of the results with a limited number of oscillator quanta.
