New results in the CBF theory for medium-heavy nuclei
نویسنده
چکیده
Momentum distributions, spectroscopic factors and quasi-hole wave functions of mediumheavy doubly closed shell nuclei have been calculated in the framework of the Correlated Basis Function theory, by using the Fermi hypernetted chain resummation techniques. The calculations have been done by using microscopic two-body nucleon-nucleon potentials of Argonne type, together with three-body interactions. Operator dependent correlations, up to the tensor channels, have been used.

Recent Results in Cbf Theory for Medium-heavy Nuclei
We extend the correlated basis functions theory (CBF) for nuclei with N 6= Z and j-j coupling scheme. By means of the Fermi hypernetted chain integral equations, in conjunction with the single operator chain approximation (FHNC/SOC), we evaluate the ground state and the one-body densities for Ca,Ca and Pb nuclei. The realistic Argonne V8’ two-nucleon potentials has been used. We compare the gro...

متن کاملThe Ground State of Medium-heavy Nuclei with Non Central Forces
Correlated Basis Function (CBF) theory is a powerful tool to investigate the properties of many-body strongly interacting systems in several fields of physics. Its first succesful applications are found in homogeneous systems such as liquid Helium, electron systems (both in the forms of electron fluids and lattice structures) and infinite nuclear and neutron matter. The flexibility of CBF based...

Correlated basis function theory and Fermi hypernetted chain technique are extended to study medium-heavy, doubly closed shell nuclei in the jj coupling scheme, with different single-particle wave functions for protons and neutrons and isospin-dependent two-body correlations. Central semirealistic interactions are used. Ground-state energies, one-body densities, distribution functions and momen...
متن کاملThreshold suppression of Λ spin-orbit splitting
New experimental data on medium to heavy single Λ hypernuclei revealed a much larger spin-orbit splitting than observed in older measurements of light hypernuclei. Taking into account particle threshold effects and the density-dependence of inmedium coupling constants the apparent suppression of spin-orbit strength in light hypernuclei as well as the spin-orbit structure observed in medium to h...
