eigenfunctions of the Holstein radiation-trapping equation. | ||

Authors: A.F. Molisch, B.P. Oehry, W. Schupita, G. Magerl | ||

Program title: RAD-TRAP | ||

Catalogue identifier: ACLB_v1_0Distribution format: gz | ||

Journal reference: Comput. Phys. Commun. 74(1993)81 | ||

Programming language: Fortran. | ||

Computer: VAX 3100. | ||

Operating system: VMS. | ||

RAM: 500K words | ||

Word size: 32 | ||

Keywords: Trapping radiation, Radiative transfer, Fredholm integral Equations, Lifetime measurements, Lineshape measurements, Eigenvalues. | ||

Classification: 21.2. | ||

Nature of problem:Computation of the eigenvalues and eigenfunctions of the Holstein integral equation describing radiation trapping in an atomic vapor (in one-dimensional geometries). | ||

Solution method:Reduction of the Fredholm integral equation of the second kind to an algebraic eigenvalue problem which is solved by standard methods. | ||

Restrictions:Restrictions of the achievable accuracy by memory and run-time limitat- ions. | ||

Unusual features:Uses subroutines from a standard library of mathematical subprograms, NAGLIB. | ||

Running time:Strongly dependent on the chosen geometry, the lineshape, the opacity and especially the required accuracy; will be between 1 and 1000 CPU seconds in most practical cases. |
