Af. Molisch et al., RAD-TRAP 2, A PROGRAM FOR THE SOLUTION OF THE HOLSTEIN EQUATION OF RADIATION TRAPPING, Computer physics communications, 77(2), 1993, pp. 255-262
RAD-TRAP computes the solution of the Holstein equation of radiation t
rapping for three important geometries: plane-parallel slab, long cyli
nder, and sphere. The new version 2 offers the direct computation of t
he steady-state distribution of excited atoms and the computation of t
he emergent spectra; effects like self-reversal can now be studied. It
also includes a new algorithm for a more efficient, highly accurate c
omputation of the cylinder case. The new version also runs on IBM-PCs.
