    "abstract": "We perform large-space shell-model calculations for the low-lying energy\nspectra of a few light nuclei, $^4\\mbox{He}$, $^5\\mbox{He}$, $^6\\mbox{Li}$ and\n$^7\\mbox{Li}$, in a no-core model space with a realistic effective two-body\ninteraction (Brueckner G-matrix). Our G-matrices are calculated for the\nReid-soft-core potential in a harmonic oscillator basis. Single-particle ``-U\u0027\u0027\ninsertions are replaced by two-particle ``-U\u0027\u0027 insertions and are included in\nthe G matrix calculations, which sum them to all orders. With the starting\nenergy of the G-matrix chosen to give approximately the experimental binding\nenergy, we obtain nuclear energy spectra which are in reasonable agreement with\nexperiment. We also investigate the dependence of our results on the size of\nthe model space and on the harmonic oscillator basis parameter ($\\hbar\\Omega$).",
