摘要

Abstract

Ab initio, calculations of nuclei face the challenge of simultaneously describing strong short-range internucleon correlations and the long-range properties of weakly-bound halo nucleons. Natural orbitals, which diagonalize the one-body density matrix, provide a basis which is better matched to the physical structure of the many-body wave function. We demonstrate that the use of natural orbitals significantly improves convergence for ,ab initio, no-core configuration interaction calculations of the neutron halo nucleus ,6,He, relative to the traditional oscillator basis.
