SP ( Stopping Power ) and IMFP ( Inelastic Mean Free Path) of lanthanum alumínate (La 2 O 3 ) x (Al 2 O 3 ) 1–x was varied with x = 0.25, 0.34, and 0.5. for electron energy from 300 eV to 50 keV have been determined by using composite Simpson from the equation of Born Ochkur correction. The main parameter in determining the SP and IMFP is Energy Loss Function (ELF) which was obtained from the experimental reflection electron energy loss (REELS) spectra. The method in this study is convenient methods for determining SP for binary compound lanthanum aluminate.
