RAD-TRAP 2, a program for the solution of the Holstein equation of radiation trapping

Abstract
RAD-TRAP computes the solution of the Holstein equation of radiation trapping for three important geometries: plane-parallel slab, long cylinder, and sphere. The new version 2 offers the direct computation of the steady-state distribution of excited atoms and the computation of the emergent spectra; effects like self-reversal can now be studied. It also includes a new algorithm for a more efficient, highly accurate computation of the cylinder case. The new version also runs on IBM-PCs. ...

Title of program: RAD-TRAP 2
Catalogue Id: ACLB_v2_0 [ACNX]

Nature of problem
Computation of the eigenvalues and eigenfunctions of the Holstein integral equation (describing radiation trapping in an atomic vapor) and the steady-state distribution of excited atoms in one-dimensional geometries.
