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

Abstract

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
????????
2 has been over estimated since the speed of electron is below
3????108
. 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 massenergy formula underestimates the electron stopping power because
of their high excitation energies. We hereby recommend this nonrelativistic mass-energy equivalence in the measurement of masses
of various particles in low and high energy states to replace the
relativistic mass-energy ????????
2which 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
