| Popis: | 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 6He, relative to the traditional oscillator basis. Comment: 6 pages, 4 figures; presented at the Symposium on Nuclear Dynamics and Thermodynamics, Huizhou, China, December 11, 2016; as published in Nucl. Sci. Tech |
