Comparison of Two- and Three-Nucleon Isoscalar Charge form Factors

Relations between isoscalar charge form factors of two- and three-nucleon systems

“…The parameters a, b and c are chosen to make the deuteron charge form factor F Once a, b and c are determined individually for each employed potential, the deviation between estimated and calculated deuteron charge form factors falls below 30% for momentum transfers The relation of Fig. 2(a) for the diffraction minimum Q 2 min passes the experimental data in their present error bars by a substantial margin; that fact is another illustration for our earlier observation [16] that the existing range of realistic nonrelativistic two-nucleon potentials together with the present understanding of meson-exchange currents is unable to account simultaneously for the e.m. properties of the two-and three-nucleon systems. That observation has serious implications.…”

“…[15]; preliminary results are published in Ref. [16]. Their effects on the deuteron and trinucleon charge form factors are strikingly similar, suggesting correlations between the theoretical predictions for them.…”

“…[11], the present calculation of e.m. trinucleon properties is improved as described in Ref. [16]. Against the tradition of the authors [9,11,21], the trinucleon calculations displayed in Figs.…”

Elastic electron scattering from light nuclei

“…The Hannover group [29,153,154,155,156] has performed calculations for various N-N potentials (Paris, Bonn-A,B,C,..). For the nucleonic form factors the authors use the Hoehler parameterization.…”

Meson and Quark Degrees of Freedom and the Radius of the Deuteron

“…[27], and our use of it is described in Ref. [28]. Consistency of the meson-exchange currents with the underlying two-nucleon potential in form, i.e., with respect to the hadron form factors and with respect to the off-shell extrapolation parameters (µ, ν), and in meson content is required.…”
