Multiquark systems in 3He and 3H and elastic electron scattering at large transfer momenta

It is shown that including six- and nine-quark admixtures with probabilities C22 = 15.4% and C32 = 0.54% into the wave functions of the 3He and 3H nuclei allows one to explain the behaviour of the elastic form factors of electron scattering in the whole region of measured transfer momenta. The interference of the nucleon, six-quark, and nine-quark channels is found to be of great importance; as a result the weights of the six-quark and nine-quark components in the form factors result to be 2% and 0.01%, respectively. 44 refs.; 7 figs.; 1 table
