A shell-model calculation in terms of correlated subsystems
2014 A method for solving the shell-model equations in terms of a basis which includes correlated subsystems is presented. It is shown that the method allows drastic truncations of the basis to be made. The corresponding calculations are easy to perform and can be carried out rapidly.

متن کاملCalculation of shell frequency distributions obtained with shell-mapping schemes
| In order to calculate the transmit power in shell{mapping{based transmission schemes, the frequencies of the shells are required. In this paper, a simple but general method for the calculation of these frequencies is derived. The method has approximately the same complexity as the shell{mapping encoder. As an example, the method is shown in detail for the shell{mapping scheme speci ed for the...
متن کاملv 1 2 J un 1 99 4 Truncation Method for the Shell Model Calculation
A method of truncating the large shell model basis is outlined. It relies on the order given by the unperturbed energies of the basis states and on the constancy of their spreading widths. Both quantities can be calculated by a simple averaging procedure. The method is tested in the sd shell where the JT dimensions are of the order of a few thousand. It proves to be very effective in the middle...
متن کاملShell-model calculation for two-neutrino double beta decay of 48Ca.
The 2vPP decay matrix element of 'Ca has been studied in a large basis shell-model space. The theoretical and experimental p and p+ spectra and their relation to 2vpp are discussed. A new empirical effective interaction is found to give the best agreement to p and p+ spectra with the effective Gamow-Teller operator 0 t =0.770t. The predicted Tl ~2 =1.9X 10' yr differs by a factor of 2 from the ...
متن کاملRealistic shell model calculation of 2νββ nuclear matrix elements and role of shell structure in intermediate states
We discuss two conditions needed for correct computation of 2νββ nuclear matrix-elements within the realistic shell-model framework. An algorithm in which intermediate states are treated based on Whitehead’s moment method is inspected, by taking examples of the double GT+ transitions 36Ar → 36S, 54Fe → 54Cr and 58Ni → 58Fe. This algorithm yields rapid convergence on the 2νββ matrix-elements, ev...
