The mathematical shell model underlying general shell elements
We show that although no actual mathematical shell model is explicitly used in ‘general shell element’ formulations, we can identify an implicit shell model underlying these nite element procedures. This ‘underlying model’ compares well with classical shell models since it displays the same asymptotic behaviours—when the thickness of the shell becomes very small—as, for example, the Naghdi mode...
متن کاملShell-model Monte Carlo studies of fp-shell nuclei.
We study the gross properties of even-even and N = Z nuclei with A = 48 64 using shell-model Monte Carlo methods. Our calculations account for all 0 h! con gurations in the fp-shell and employ the modi ed Kuo-Brown interaction KB3. We nd good agreement with data for masses and total B(E2) strengths, the latter employing e ective charges ep = 1:35e and en = 0:35e. The calculated total Gamow-Tell...
متن کاملLarge-basis shell-model calculations for p-shell nuclei
Results of large-basis shell-model calculations for nuclei with A = 7 − 11 are presented. The effective interactions used in the study were derived microscopically from the Reid93 potential and take into account the Coulomb potential as well as the charge dependence of T = 1 partial waves. For A = 7, a 6h̄Ω model space was used, while for the rest of the studied nuclides, the calculations were p...
متن کاملA Multi-Shell Shell Model for Heavy Nuclei
Performing a shell model calculation for heavy nuclei has been a long-standing problem in nuclear physics. Here we propose one possible solution. The central idea of this proposal is to take the advantages of two existing models, the Projected Shell Model (PSM) and the Fermion Dynamical Symmetry Model (FDSM), to construct a multi-shell shell model. The PSM is an efficient method of coupling qua...
متن کاملAnisotropic shell model of turbulence.
An anisotropic shell model has been proposed for two-dimensional (2D) turbulence. It is similar to the 2D version of the Gledzer-Ohkitani-Yamada model but with the angular variable in wave-number space divided into three distinct directions representing structures elongated in different directions. In the case when the drive is isotropic the usual isotropic solution is recovered as the fixed po...
