چکیده
Correlated basis function theory and Fermi hypernetted chain theory are extended to treat finite Fermi systems . In this first paper, the effects of the scalar nucleon-nucleon correlations are investigated by studying some model N = Z nuclei . Results of calculations performed using central nucleon-nucleon potentials, without tensor components, are presented and are compared with results from other theories .

متن کاملModel calculations of doubly closed shell nuclei in CBF theory III . j j coupling and isospin dependence
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 کاملNew results in the CBF theory for medium-heavy nuclei
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 interact...
متن کاملShell-Model Calculations with Realistic Effective Interactions
In this paper, we present some results of shell-model calculations employing effective interactions derived from the CD-Bonn free nucleon-nucleon potential. These concern 18O, 134Te, and 210Po, and are part of a comprehensive study of nuclei around doubly closed shells. Comparison of the calculated results with experimental data illustrates the degree of accuracy of modern realistic shell-model...
متن کاملShell-model calculations for neutron-rich nuclei in the Oflp shell
A new two-body interaction recently derived for nuclei in the 0flp shell by fitting two-body matrix elements to 494 energy levels in A = 41-66 nuclei, is used to investigate the neutron-rich nuclei in the vicinity of the doubly closed nuclide 48Ca. This study is of fundamental interest in providing a test for the new effective interaction away from the stability line. Masses and binding energie...
