    "abstract": "We have calculated the ground-state energy of the doubly-magic nucleus 40Ca\nwithin the framework of the Goldstone expansion using the CD-Bonn\nnucleon-nucleon potential. The short-range repulsion of this potential has been\nrenormalized by integrating out its high-momentum components so as to derive a\nlow-momentum potential V-low-k defined up to a cutoff momentum Lambda. A simple\ncriterion has been employed to establish a connection between this cutoff\nmomentum and the size of the two-nucleon model space in the harmonic oscillator\nbasis. This model-space truncation approach provides a reliable way to\nrenormalize the free nucleon-nucleon potential preserving its many-body\nphysics. The role of the 3p-3h and 4p-4h excitations in the description of the\nground state of 40Ca is discussed.",
