Thin solid films of N/sub 2/, O/sub 2/, Ar, Kr, and Xe were condensed on a cooled (11 K) sapphire substrate and then bombarded by monoenergetic electrons. The fluorescence intensity of the Cr/sup 3 +/ color center in sapphire (lambda=693 nm) was measured as a function of film thickness and electron energy to determine the electron practical range and effective energy loss (dE/dz). The Cr/sup 3 +/ intensity versus primary-electron-energy and film-thickness curves also yield information on the production of secondary electrons. The results are compared to an extrapolation of Bethe-Bloch theory to low energies for total range and energy loss (dE/ds) and to the electron-gas statistical model of Tung, Ashley, and Ritchie for low-energy electrons.
