Gogny force

WebJul 6, 2024 · Nowadays, the Gogny force is a referent in the theoretical description of nuclear structure phenomena. Its phenomenological character manifests in a simple analytical form that allows for implementations of techniques both at the mean field and beyond all over the nuclide chart. WebTwo theoretical nuclear models, Hartree-Fock plus pairing in the BCS approximation (HF-BCS) with Skyrme SLy6 parametrization and Hartree-Fock-Bogolyubov (HFB) with Gogny D1S force, are used to calculate the nuclear masses.

WebMay 25, 1998 · The Gogny type finite range force has a better treatment of the coupling to the highly excited states but it is density-independent and its finite range property involves more complicated numerical techniques. Here we report on the RCHB theory and provide details of the relevant numerical techniques. Webheavy-ion collisions [43,52]. Similar to the Gogny case, the MDI force may be expressed as a zero-range contribution plus a finite-range term, but with a Yukawa form factor instead of a Gaussian. A parameter x of the MDI interaction can be varied to modify the uncertain density dependence of the symmetry energy and of the download photoshop tinhte https://yangconsultant.com
