We consider the three-nucleon system within an effective theory with contact interactions at leading order in the large scattering length. We calculate the charge form factor of the triton at low momentum transfer and extract the triton charge radius. At this order, no two-body currents contribute and the calculation can be performed in the impulse approximation. We also comment on the power counting for higher orders. The requirement of a three-body force for renormalization of the three-nucleon system explains the previously observed correlation between the triton binding energy and charge radius for different model potentials.Comment: 11 pages, 2 eps figures, revtex4, version to appear in Nucl.

“…The baryon density distribution in 3 He is calculated from the charge densities of 3 He and 3 H. Fig. 1 shows the neutron charge form factor with R 0 = 1.0 fm, using two different experimental fits to the charge distribution (FB refers to a Fourier-Bessel fit [26] and SOG to a fit using a Sum-of-Gaussians [27]). The πNN coupling constant is taken to have its free space value in these calculations.…”

In order to measure the charge form factor of the neutron, G n E (Q 2 ), one needs to use a neutron bound in a nuclear target. We calculate the change in the form factor for a neutron bound in 3 He, with respect to the free case, using several versions of the quark meson coupling model. It is found that the form factor may be suppressed by as much as 12% at Q 2 = 0.5 GeV 2 with respect to that of the free neutron.

“…Therefore, it is reasonable, first, to determine the wave functions by fitting the experimentally measured form factors of the three-nucleon nuclei, [1][2][3][4][5][6][7][8][9] and then to use these wave functions for the calculation of the cross sections of the 3 H and 3 He interactions with nuclei. On the other side, the electromagnetic form factors give the most accurate experimental information on these wave functions.…”

The nonrelativistic wave functions of 3 H and 3 He nuclei have been obtained on the basis of the experimentally measured charge form factors. The differential cross section of the elastic 3 He-nucleus scattering has been calculated with the help of the wave function derived. This cross section agrees with the experimental data on the elastic scattering of 3 He by 90 Zr, 120 Sn, and 208 Pb nuclei at 130 and 217 MeV. The integrated cross sections of various processes of 3 H and 3 He interaction with heavy nuclei have also been calculated.
