Influence of the short range nonlocal nucleon-nucleon interaction on the elasticn−dscattering: Below30MeV

Abstract

A previously defined short range nonlocal nucleon-nucleon (NN) interaction, which more closely matches common expectations and reproduces the 3 H and 3 He binding energies, is tested in elastic scattering. Nonlocal P-wave interactions with modified on-shell behavior were constructed in order to produce better low-energy n -d analyzing powers. At low energies some of the changes are due to the correct 3N binding energy, however, there are effects due to the characteristic properties of the nonlocal interactions. There is an indication that p -d calculations based on the present nonlocal NN interactions (with or without the modified P-wave interactions) would produce the same quality or better agreement with the low-and medium-energy experimental data than the corresponding local NN interaction plus 3N force model.

“…Consequently, the off-shell behavior of the CD-Bonn interaction differs from local potentials which leads to larger binding energies in nuclear few-body systems. A new type of interaction, which respects the local behavior of traditional NN interactions at longer ranges but exhibits a non-locality at shorter distances, was recently proposed by Doleschall et al [10,11]. The authors explore the extent to which effects of multi-nucleon forces can be absorbed by non-local terms in the NN interaction.…”

“…As already mentioned, we test two different, highprecision NN interactions in this study: the CD-Bonn 2000 [9] and the INOY [10,11] potentials.…”

“…In this paper, we calculate the ground-state properties of 4 He, 6 He and 8 He within the NCSM. We test two vastly different accurate nucleonnucleon (NN) potentials, the CD-Bonn [9] and the the INOY (Inside Nonlocal Outside Yukawa) [10,11].In the NCSM, we consider a system of A point-like non-relativistic nucleons that interact by realistic two-or two-plus three-nucleon interactions. The calculations are * etienne.caurier@ires.in2p3.fr † navratil1@llnl.gov performed using a finite harmonic oscillator (HO) basis.…”

“…[16,[26][27][28]. We use several realistic interaction models, i.e., the charge-dependent Bonn potential (CD Bonn) [29], its coupled-channel extension CD Bonn + Δ [30], and the inside-nonlocal outside-Yukawa (INOY04) potential by Doleschall [6,31]. The latter yields nearly the experimental value for the 3 He and 3 H binding energy without an additional three-nucleon force.…”
