β¦ Synopsis
Radiation trapping is described by the Holstein equation, a Fredholm integral equation of the second kind. By combining analytical and numerical techniques, the presented code efficiently computes the eigenvalues and eigenfunctions of this equation for three important geometries: plane-parallel slab, long cylinder, and spherically symmetric geometry; all practically occurring spectral lineshapes are considered. The program is written in standard Fortran.

McTrap computes radiation trapping including bleaching effects and particle diffusion in a two-dimensional cylinder geometry. It combines Monte Carlo simulations of radiation trapping and analytical solutions of the diffusion equation for a highly efficient computation of the distribution of excited
Two computer programs (FGHEVEN and FGHFFT) for solving the one-dimensional Schrodinger equation for bound-state eigenvalues and eigenfunctions are presented. Both computer programs are based on the Fourier grid Hamiltonian method (J. Chem. Phys. 91(1989) 3571). The method is exceptionally simple and
Eigenfunctions and eigenvalues of the Schrtiinger equation are determined by propagating the Schrodinger equation in imaginary time. The method is based on representing the Hamiltonian operation on a grid. The kinetic energy is calculated by the Fourier method. The propagation operator is expanded i
