Nonempirical Interactions for the Nuclear Shell Model: An Update

Effective Interactions for the Nuclear Shell Model

Effective interactions for the nuclear shell model

Various perturbative and non-perturbative many-body techniques are discussed in this work. Especially, we will focus on the summation of so-called Parquet diagrams with emphasis on applications to finite nuclei. Here, the subset of two-body Parquet equations will be discussed. A practical implementation of the corresponding equations for studies of effective interactions for finite nuclei is ou...

Test of shell-model interactions for nuclear structure calculations.

Recently no-core shell-model calculations have been performed @1,2#, in which all nucleons are active, so there are no hole states. This approach avoids the use of shell-model effective interactions involving excitations from an inert core of nucleons ~e.g., the core-polarization process!, and thereby avoids the convergence problems of the standard effectiveinteraction approach @3#. In this pap...

Beyond the nuclear shell model

© 2007 American Institute of Physics, S-0031-9228-0711-030-9 Nuclei, the fuel that burns in stars, make up 99.9% of all baryonic matter in the universe.1 The complex nature of the nuclear forces among protons and neutrons generates a broad range and diversity of nuclear phenomena. Developing a comprehensive description of nuclei and their reactions represents one of the great intellectual oppor...

EfFective interactions for the OplsOd nuclear shell - madel space

Shell-model interactions are constructed in the cross-shell model space connecting the Op and ls0d shells with due regard for the perturbative efFects of the neighboring Os and Oflp shells. The interactions have three distinctive Op-shell, cross-shell, and 1sOd-shell parts. The latter is taken to be the previously determined W interaction. The Op-shell interaction is represented by two-body mat...
