    "abstract": "The Lee-Suzuki iteration method is used to include the folded diagrams in the\ncalculation of the two-body effective interaction $v^{(2)}_{\\rm eff}$ between\ntwo nucleons in a no-core model space. This effective interaction still depends\nupon the choice of single-particle basis utilized in the shell-model\ncalculation. Using a harmonic-oscillator single-particle basis and the\nReid-soft-core {\\it NN} potential, we find that $v^{(2)}_{\\rm eff}$ overbinds\n$^4\\mbox{He}$ in 0, 2, and $4\\hbar\\Omega$ model spaces. As the size of the\nmodel space increases, the amount of overbinding decreases significantly. This\nproblem of overbinding in small model spaces is due to neglecting effective\nthree- and four-body forces. Contributions of effective many-body forces are\nsuppressed by using the Brueckner-Hartree-Fock single-particle Hamiltonian.",
