Continuous slowing‐down approximation range of 50‐keV–100‐MeV electrons

摘要

The Wilson theory has been modified for the calculation of the continuous slowing‐down approximation (CSDA) range of 50‐keV–100‐MeV electrons in the absorbers of atomic numbers from 1 to 92 and in some detector materials, minerals, organic compounds, and gaseous compounds. A correction factor which depends on energy as well as on atomic number is evaluated. Values of the CSDA range obtained by the present approach have shown an agreement with reported values within a discrepancy of 6–7%. An attempt has also been made to correlate the CSDA range with the available experimentally measured projected range. Calculated projected range and experimentally measured projected range are found to be in good agreement.
