The nucleon-nucleon correlations of asymmetric nuclear matter (ASM) in the 3S1-3D1 and 3P2-3F2 states with AV18 AV’6 potentials are studied lowest order constrained variational (LOCV) method. In these computations, tensor (or spin-orbit) considered (3P2-3F2) state. energy, as well healing distance ASM mentioned states, reported. It is demonstrated that by decreasing proton to neutron ratio, non...

Present day chiral nucleon-nucleon potentials up to next-to-next-tonext-to leading order and three nucleon forces at next-to-next-to leading order are used to analyze nucleon-deuteron radiative capture at deuteron laboratory energies below Ed ≈ 100 MeV. The differential cross section and the deuteron analyzing powers Ay(d) and Ayy are presented and compared to data. The theoretical predictions ...

The astrophysical S-factor for the proton weak capture on 3He is calculated with correlated-hyperspherical-harmonics bound and continuum wave functions corresponding to realistic Hamiltonians consisting of the Argonne v14 or Argonne v18 two-nucleon and Urbana-VIII or Urbana-IX three-nucleon interactions. The nuclear weak charge and current operators have vector and axial-vector components, that...

With the advent of new radioactive beam facilities like FAIR, the structure of exotic nuclei far beyond the valley of stability can be probed experimentally, providing a strong motivation for theoretical studies using ab initio approaches and interactions which provide a stringent link to QCD as the fundamental theory of the strong interaction. To this end, we apply second-generation VUCOM inte...

Two independent calculations of proton-deuteron elastic scattering observables including Coulomb repulsion between the two protons are compared in the proton lab energy region between 3 MeV and 65 MeV. The hadron dynamics is based on the purely nucleonic charge-dependent AV18 potential. Calculations are done both in coordinate space and momentum space. The coordinate-space calculations are base...

Variational Monte Carlo wave functions, obtained from a realistic Hamilto-nian consisting of the Argonne v 18 two-nucleon and Urbana-IX three-nucleon interactions, are used to calculate the 6 Li ground-state longitudinal and transverse form factors as well as transition form factors to the first four excited states. The charge and current operators include one-and two-body components , leading ...

The equation of state (EoS) neutron star (NS) matter is investigated considering kaon condensation. Moreover, the tidal parameters related to components binary mergers are determined and compared constraints GW170817 imposed on these quantities. In this study, we employ lowest-order constrained variational (LOCV) approach utilize {AV6$'$, AV8$'$, AV18 potentials} accompanied by three nucleon in...
