Abstract
The theoretical computations of the electron–nucleus scattering can be improved, by employing the asymmetric nuclear matter (ASM) two-body density distributions (TBDD). But, due to the sophistications of the calculations, the TBDD with arbitrary isospin asymmetry have not yet been computed in the Fermi Hypernetted Chain (FHNC) or the Monte Carlo (MC) approaches. So, in the present work, we intend to find the ASMTBDD, in the states with isospinT, spin S and spin projection Sz, in the Lowest Order Constrained Variational (LOCV) method. It is demonstrated that, at small relative distances, independent of the proton to neutron ratio β, the state-dependent TBDD have a universal shape. Expectedly, it is observed that, at low (high) β values, the nucleons prefer to make a pair in the T=1(0) states. In addition, the strength of the tensor-dependent correlations is investigated, using the ratio of the TBDD in the TSSz=010 state with θ=π∕2 and that of θ=0. The mentioned ratios peak at r∼0.9fm, considering different β values. It is hoped that, the present results could help a better reproduction of the experimental data of the electron–nucleus scattering.
