Calculation of Electron Stopping Power in Some Material Targets Using New Mass-Energy Concept

In this study, the new mass- energy concept theory, mbc, has been employed in the Beth-Bloch stopping power formula to calculate the total stopping power of electron in some materials, namely, air, tissue, water, skeletal muscle, plastic, copper and lead within the energy range of 0.01MeV to 1000MeV.The mass-energy formula  has been over estimated since the speed of electron is below . Therefore, the electron stopping power for low mass density materials: air, tissue, water, skeletal muscle and plastic and such others are lower for the mbc mass-energy formula; while for high mass density materials like copper and lead, the Einstein’s mass-energy formula underestimates the electron stopping power because of their high excitation energies. We hereby recommend this non-relativistic mass-energy equivalence in the measurement of masses of various particles in low and high energy states to replace the relativistic mass-energy which results in various applications in nuclear physics and chemistry. The new mass – energy concept mbc can be employed in nuclear binding energy calculations for the investigation and interpretation of nuclear structure and nuclear reactions. The universal particle speed constant, b, can be applied in relating the frequencies and wavelengths of nuclear and elementary particles
