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

Abstract

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

Nonlocality and the D-state Probability of the Deuteron

“…The inclusion of this nonlocality in the D state, in addition to the S state, in the potential of Mustafa et al (1992) may be partially the reason for its giving the smaller value of PD = 6·29%, a result that one would expect from the findings of the present work.…”

“…of Mustafa et al (1992) has also been found in the w wavefunctions of the present work, as shown in Fig. 4.…”

“…Attractive short-range nonlocality was incorporated into the S channel in the deuteron potential of Kermode et al (1991aKermode et al ( , 1991b and in 'both' the Sand D channels in the deuteron potential of Mustafa et al (1992). In the latter case, no pronounced effect was found in deuteron properties as a result of introducing attractive nonlocality into the D state (in addition to the S state) because of the relatively small role of the D state in comparison with that of the S state.…”

Deuteron stripping on nuclei at intermediate energies

“…Here, the parameter ξ = 0.049 fm −2 was so chosen that (27) would reproduce the experimental root-mean-square radius of deuteron [12]. The dash-dotted curves reproduce the results of cross section calculations made in work [17] in the framework of the virtual pion exchange model.…”

“…Correlations between the slope b of the neutron form factor G En (q 2 ) at q 2 = 0 and the deuteron root mean square (rms) matter radius r D for different NN-potential models have been used to determine r D [15,16,17].…”
