Multiquark configuration effect on nuclear charge form factors in hadron-quark hybrid model

High-energy electron scattering from nuclear target has revealed features that were not known before. A number of nuclear theoretical approaches have been made to explain the elastic electron scattering from helium isotopes in the region of large momentum transfers. A multiquark clustering effect is invoked to supplement the ordinary nuclear theoretical approach in explaining the nuclear form factors of light nuclei, namely³He,⁴He, and⁶Li. In all these three nuclei it is observed that ordinary nuclear-physics component dominates in the region of low momentum transfer but decreases with increasing the momentum transfer. The multiquark components become dominant in the higher-momentum-transfer regions.
