Many research studies the loss of ion energy in chemicals and materials, because this subject has a great interest for multiple applications in material science and atomic physics. Proton loses its energy when interacting with oxides such as Al2O3 and ZrO2. In the current work under the formalities of insulation, the calculations were performed by combination of Durde energy loss functions with a generalized oscillator to describe the electrons in the outer and inner cascades sequentially. Provides a realistic description of the electronic properties of each goal of this method. Comparable cross sections are compared fairly well with a wide range of proton energies with experimental data available. The non-free average path parameter (IMFP) is calculated because the most important in surface-sensitive quantitative spectral analysis (IMFP) can be determined as a average distance between an electron and a given energy between successive non-elastic collisions. Another parameter describes the angular distribution of the extruded electron. This parameter is known as the differential cross-section, thus obtaining the energy distribution of the electrons produced by each proton from the corresponding cross-section.
