Realistic Effective Interactions and Nuclear Structure Calculations
We address the two main questions relevant to microscopic nuclear structure calculations starting from a free NN potential. These concern the accuracy of these kinds of calculations and the extent to which they depend on the potential used as input. Regarding the first question, we present some results obtained for nuclei around doubly magic Sn and Pb by making use of an effective interaction d...
متن کاملNuclear Structure and Response based on Correlated Realistic NN Interactions
Starting from the Argonne V18 nucleon-nucleon interaction and using the Unitary Correlation Operator Method, a correlated interaction vUCOM has been constructed, which is suitable for calculations within restricted Hilbert spaces. In this work we employ the vUCOM in Hartree-Fock, perturbation-theory and RPA calculations and we study the ground-state properties of various closed-shell nuclei, as...
متن کاملRealistic and Effective Interactions in the Study of Nuclear Matter
The equation of state of symmetric nuclear matter is addressed starting both from a realistic interaction derived from nucleon-nucleon scattering processes and from a low-momentum effective potential. The approach is based on finite temperature Green's functions. The internal energy per particle is estimated from the summation of diagrams and through the Galitskii-Koltun's sum rule. At present,...
متن کاملRandom versus realistic interactions for low-lying nuclear spectra.
We compare the shell-model results for realistic interactions with those obtained for various ensembles of random matrix elements. We show that, although the quantum numbers of the ground states in the even-even nuclei have a high probability ( approximately 60%) to be J(pi)T = 0(+)0, the overlap of those states with the realistic wave functions is very small in average. The transition probabil...
متن کاملIn Medium T Matrix with Realistic Nuclear Interactions *
PACS numbers: 21.65.+f The presence of a strong interaction between nucleons at short distances requires the use of resummation methods for many-body calculations in nuclear matter. Besides the Brueckner-Hartree-Fock (BHF) summation of ladder diagrams [1, 2] and advanced variational methods [3, 4], the self-consistent in-medium T -matrix approach became feasible in last years [5, 6, 7, 8, 9]. T...
