Abstract

We use the AV8' nucleon-nucleon potential renormalized with the Lee-Suzuki prescription with the Hybrid Multideterminant scheme to evaluate energies of some light nuclei. The Lee-Suzuki prescription is used to evaluate the the two-body matrix elements up to 6 major oscillator shells in the lab frame. The Hybrid Multideterminant scheme is used to deal with the nuclear-structure problem. The results obtained for ⁶Li, ¹²C and ¹⁶O are compared with the results obtained with other methods. The results suggest a reasonable convergence of the renormalization prescription for 6 major shells.
