Multiple-charged beams originating from a 300-kv ion accelerator are important tools in the study of metal surfaces and thin films. A knowledge of the particle range is necessary for an understanding of the interaction processes of the ions with the targets. Utilizing a theory developed by lindhard for determining the range of low-energy ions in solids, the ranges of h, he, c, n, o, and ar ions in al2o3, al, fe2o3, fe3o4, cuo, cu2o, fe, cu, sn, and w were calculated for the energy range 60 to 400 kev using a computer program written in basic. The range, presented in graphical form, is given in both ug/cm2 and angstroms. In addition, heavy ion ranges were calculated for comparison with published experimental values. For ions with z > 5, the discrepancy between the calculated values and published experimental values generally ranged from 2 to 40 percent; the largest deviations were probably due to experimental error.
