Phenomenological high precision neutron–proton delta-shell potential

Abstract: We provide a succesful fit for neutron-proton scattering below pion production threshold up to LAB energies of 350MeV. We use seven high-quality fits based on potentials with different forms as a measure of the systematic uncertainty. We represent the interaction as a sum of delta-shells in configuration space below the 3fm and a charge dependent one pion exchange potential above 3fm together with electromagnetic effects. Special attention is payed to estimate the errors of the phenomenological interaction.

“…Similar remarks apply to [8] where B num t = 0.1 keV. Based on general arguments, attempts have also been made to quantify the systematic uncertainties in nuclear bindings stemming from NN scattering [16,26,27]) yielding E sys /A = 100-500 keV, in rough agreement with the more sophisticated three-body estimate of 340 KeV above. This suggests using the present calculation as a benchmark in approximate error estimates, sidestepping the full-fledged calculation.…”

“…Since the Nijmegen group analysis in 1993 [11] a set of high quality potentials have emerged fitting their contemporary databases [12][13][14][15][16][17][18][19][20][21]. However, the self-consistency of the χ 2 approach requires the residuals to be normally distributed, …”

“…In previous works we have advocated a coarse grained approach [12,32,33] for the unknown interaction below the elementariness radius r c = 3 fm that gives the best quality fit to NN data below a laboratory (LAB) energy of 350 MeV [11]. This maximum energy corresponds to maximal CM momentum p max ∼ √ Mm π .…”
