“…extrapolated from realistic NN interactions con-' straining t/ to be given by (6) and making assumptions on the neutron electric form factor G~, at small momentum transfers consistent with the recent quark model prediction for G~, of Isgur et al [13] as well as, for comparison purposes, the earlier value r d = 1.9635 +0.0045 fm [14]. The values Of QD used in (2) are the experimental value of 0.2860_+0.0015fm 2 [15] and the value QD=0.2790 fmZ which takes into consideration a minimum contribution of 0.007 fm 2 to QD from MEC, relativistic effects and IC [16][17][18], as should be the case in the impulse approximation expression used. The Reid soft-core (RSC) potential [19] has been assumed outside R=2.0fm.…”

“…The results using the earlier experimental value r e = 1.9635 fm [14] are also shown. If it were possible to determine As more accurately from low energy NN phase shifts (as we will discuss in the next section) then, ignoring the relatively smaller contribution to ~ from MEC, relativistic effects and IC of about 0.5% [18], a result As>O.88fm -~ would yield a lower bound on the contribution to the experimental value of QD from these effects (thought to be between 2.5 and 6 % [- [16][17][18]). …”

The asymptoticS-state amplitude of the deuteron wave function

Bounds on the asymptotic S-state amplitude As of the deuteron wave function are calculated as a function of assumed impulse approximation values for the quadrupole moment. Alternatively, for a given value of A s, a bound is obtained on the minimum contribution to the experimental value of QD from meson-exchange currents, relativistic effects and isobar contributions. The extraction of A s from low energy elastic nucleonnucleon scattering data is discussed in detail.

Nuclear matter equation of state from a quark-model nucleon-nucleon interaction

et al. 2015

Starting from a realistic constituent quark model for the nucleon-nucleon interaction, we derive the equation of state (EOS) of nuclear matter within the Bethe-Brueckner-Goldstone approach up to three-hole-line level, without need to introduce three-nucleon forces. To estimate the uncertainty of the calculations both the gap and the continuous choices for the single-particle potential are considered and compared. The resultant EOS is compatible with the phenomenological analysis on the saturation point, the incompressibility, the symmetry energy at low density and its slope at saturation, together with the high-density pressure extracted from flow data on heavy ion collisions. Although the symmetry energy is appreciably larger in the gap choice in the high-density region, the maximum neutron star masses derived from the continuous-choice EOS and the gapchoice EOS are similar and close to two solar masses, which is again compatible with recent observational data. Comparison with other microscopic EOS is presented and discussed.

“…It has been thought that the experimental value of Q is too large to be reproduced by local deuteron potentials. For example, Allen et al [20] cla. imed that the quadrupole moment of the deuteron is almost impossible to be fitted with energyindependent potentials.…”

Extracting a value of the deuteron radius by reanalysis of the experimental data

et al. 1992

View full text Add to dashboard Cite

A new value, rD=1.9546+0.0021 fm, for the rms radius of the deuteron has been extracted by reanalyzing the experimental data for the ratio R (q ) of the deuteron to proton electric form factors and for the slope of the neutron electric form factor GE"(q') at q'=0. The short-range structures in the radia1 deuteron wave functions found for a certain class of potentials (e.g. , Kermode et al. and potential models presented here) cause an increase in the model values of the deuteron charge form factor CE{q ), but have no special features in the variation of Cz(q ) with q . A new method for calculating CE(q ) accurately is presented.PACS number(s): 21.30. +y, 13.75.Cs, 21.45.+v, 21.10.Ft
