Manuscript Title: Revised calculation of four-particle harmonic-oscillator transformation brackets matrix | ||

Authors: S. Mickevicius, D. Germanas, R.K. Kalinauskas | ||

Program title: HOTB_M | ||

Catalogue identifier: AEFQ_v3_0Distribution format: tar.gz | ||

Journal reference: Comput. Phys. Commun. 184(2013)409 | ||

Programming language: Fortran 90. | ||

Computer: Any computer with Fortran 90 compiler. | ||

Operating system: Windows, Linux, FreeBSD, True64 Unix. | ||

RAM: Up to few Gigabytes (see Table 1 and Table 2 included in the distribution package) | ||

Keywords: Mathematical methods in physics, Algebraic methods, Nuclear shell model. | ||

PACS: 03.65.Fd 21.60.Cs. | ||

Classification: 17.16, 17.17. | ||

Does the new version supersede the previous version?: Yes | ||

Nature of problem:Calculation of the matrix of 4HOB in a more effective way, which allows us to calculate matrix of the brackets up to a few hundred times more rapidly than in a previous version. | ||

Solution method:The method is based on compact expressions of 4HOB, presented in [1] and its simplifications presented in this paper. | ||

Reasons for new version:We facilitated the calculation of the 4HOB, based on the method, presented in section 'Theoretical aspects'. The new program version gives shorter calculation times for the 4HOB matrices calculations. | ||

Summary of revisions:New subroutines for calculation of the matrix of 4HOB. For theoretical issues of revision see section 'Theoretical aspects'. | ||

Restrictions:The 4HOB matrices up to e = 28. | ||

Running time:Depends on the dimension of 4HOB matrix (see Table 1 and Table 2 included in the distribution file.). | ||
