Realistic collective nuclear Hamiltonian

The residual part of the realistic forces—obtained after extracting the monopole terms responsible for bulk properties—is strongly dominated by pairing and quadrupole interactions, with important στ⋅στ, octupole, and hexadecapole contributions. Their forms retain the simplicity of the traditional pairing plus multipole models, while eliminating their flaws through a normalization mechanism dictated by a universal ${\mathit{A}}^{\mathrm{-}1/3}$ scaling. Coupling strengths and effective charges are calculated and shown to agree with empirical values. Comparisons between different realistic interactions confirm the claim that they are very similar. © 1996 The American Physical Society.
