Abstract
Charge form factor reveals many features of nuclei and particles within the nuclei specially, in the higher momentum transfer region. In this work, we are concerned with 3He and 4He. In the high momentum transfer, regions it requires short range correlation effect (SRC), Masonic exchange current (MEC), D-state and quark degrees of freedom (QDF), to reproduce second minimum and third maximum in good agreement with the experimental data. Consideration of certain percentage of D-State wave function 3% for 3He and 4% for 4He Hadrons Quark Hybrid model (HQH) including interference terms produces improvement in the position of first minimum and second maximum. Contribution of QDF is found necessary with quark clusters of 3q, 6q, 9q when the inter nucleon distance becomes less than rc (critical radius). At a radius of 1.1 fm by using thermodynamic method 3q-quark clusters show higher probabilities up to 84.5% for He4 while, p6q = 12.6 %, p9q = 2.5% and p12q = 0.33 % respectively.
