Fine structure cross sections from reactance matrices — A more versatile development of the program JAJOM

Abstract

Title of program: JAJOMPRE Nature of physical problem Results from calculations with LS-coupled wave functions Catalogue number: ACYG (reactance matrices and term coupling coefficients) are used to compute collision strengths for transitions between fine Program obtainable from: CPC Program Library, Queen’s structure levels. University of Belfast, N. Ireland (see application form in this issue) Method of solution Computer: IBM 360/65, IBM 360/195, CDC 6400; InstallaThe input is carefully checked. The algebraic transformation tion: University College London, SRC/Rutherford Laboratory, uses Racahalgebra, the coefficients are computed as required. UK, JILA, University of Colorado An optional further transformation to allow for intermediate coupling in the target requires term coupling coefficients to Operating system: OS 360, scope 34 be supplied by the user. The collision strengths are computed using either of two formulae, corresponding to weak or strong coupling respectively. Programming language used: FORTRAN IV
