Ohio State University, Central Electron Optics Facility, 042 Fontana Labs, 116 W. 19th Ave. Columbus, OH 43210-1110 (614)292-0674 Abstract: This program will calculate composition of thin foils using the Cliff-Lorimer analysis of x-ray intensities. The inte- grated intensities of the peaks are entered manually and the atomic and weight concentrations are calculated using either empirical or theoretical K-factors. This program will not do spectral processing (i.e. background subtrac- tion or peak unfolding). It is most useful for teaching purposes or for those people with older versions of analy- sis software. Al Romig of Sandia Labs wrote the original version of this program using DEC PDP-11 Fortran. His work is documented in Sandia Labs report number SAND82-2938. Henk Colijn of OSU translated the program to run on an IBM PC using Microsoft Fortran v3.31. Run program CONFIG to set up the usual parameters for your microscope. Program STEM.EXE is the most general version of the program and should run on any MS-DOS machine. STEM87. EXE requires an 8087 numeric coprocessor using the IBM-PC interrupt structure.  IBM PC using Microsoft Fortran v3.31.
