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 کاملMicroscopic Nuclear Structure and Reaction Calculations in the FMD Approach
Fermionic Molecular Dynamics (FMD) is a microscopic many-body approach which has been used successfully to study the structure of light nuclei in the pand sd-shell. FMD uses a Gaussian wave packet basis which contains the harmonic oscillator shell model and Brink-type cluster model wave functions as limiting cases. A realistic effective interaction that has been derived from the Argonne V18 int...
متن کاملUtilizing Symmetry Coupling Schemes in Ab Initio Nuclear Structure Calculations
We report on ab initio no-core shell model calculations in a symmetryadapted SU(3)-based coupling scheme that demonstrate that collective modes in p-shell nuclei emerge from first principles. The low-lying states of Li, He, Be, B, C, and O, are shown to exhibit orderly patterns that favor spatial configurations with strong quadrupole deformation and complementary low intrinsic spin values, a pi...
متن کاملQuark structure and nuclear effective forces.
We formulate the quark meson coupling model as a many-body effective Hamiltonian. This leads naturally to the appearance of many-body forces. We investigate the zero range limit of the model and compare its Hartree-Fock Hamiltonian to that corresponding to the Skyrme effective force. By fixing the three parameters of the model to reproduce the binding and symmetry energy of nuclear matter, we f...
متن کاملA New Approach to Large-Scale Nuclear Structure Calculations
A new approach to large-scale nuclear structure calculations, based on the Density Matrix Renormalization Group (DMRG), is described. The method is tested in the context of a problem involving many identical nucleons constrained to move in a single large-j shell and interacting via a pairing plus quadrupole interaction. In cases in which exact diagonalization of the hamiltonian is possible, the...
