“…(5) and given in column 1. To calculate r ch from the matter radii r m [1,9,20,21,22] we use r p = 0.862(12) fm, the neutron charge radius of the respective references, the standard Darwin-Foldy contribution, r 2 DF = 0.0331 fm 2 , the spin-orbit correction for the Paris potential r 2 SO = −0.0015 fm 2 , and the non-nucleonic contribution r 2 [2] of column 3. In the last two rows the deuteron charge and matter radii are calculated from the experimental charge radius difference (r 2 ch − r 2 p ) exp = 3.795(19) fm 2 [14] and (r 2 ch − r 2 p ) exp = 3.807(26) fm 2 [23] as determined by the isotope shift of the 1s − 2s transition in atomic hydrogen.…”

The existing experimental data for the deuteron charge radius are discussed. The data of elastic electron scattering are inconsistent with the value obtained in a recent atomic physics experiment. Theoretical predictions based on a nonrelativistic description of the deuteron with realistic nucleon-nucleon potentials and with a rather complete set of meson-exchange contributions to the charge operator are presented. Corrections arising from the quark-gluon substructure of the nucleon are explored in a nonrelativistic quark model; the quark-gluon corrections, not accounted for by meson exchange, are small. Our prediction for the deuteron charge radius favors the value of a recent atomic physics experiment.

Abstract. The extension of the tensor potential S 12 VT(r) to the case of a nonlocal interaction is shown to be Vr(r, r') = S~2F(r , r')where p = r/r. This potential has the necessary invariance properties provided that F(r, r') = F(r', r). With this potential and F(r, r') taken to have a rank-one separable form, the behaviour of the model-deuteron radius with respect to the strength of the tensor nonlocality is investigated. It is found that the model radius decreases as the tensor nonlocality becomes more attractive. This is consistent with recent work which considers only central nonlocality.

“…Simon et al [3] used their measurements of R(q ) and obtained rD = 1.9625+0.0047 fm (ro = l.9560 +0.0068 fm), by fitting their data with polynomials of order three (four). Experimental data have been reanalyzed by Allen et al [4], McTavish [5], and Klarsfeld et al [6]. For the radial deuteron wave functions of a given potential model and their family of the wave functions produced by unitary transformations, Allen et al.…”

“…For the radial deuteron wave functions of a given potential model and their family of the wave functions produced by unitary transformations, Allen et al. [4] found a linear relation between ra and b. The experimental value b=0.0199+0.0003 fm given by Koester et al [8] has been used to determine rD "indirectly" from the plotted straight line.…”

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

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
