Investigation of penetration depth of 63Ni beta spectrum in silicon by Monte Carlo method and using MCNPX code

In this study, the energy spectrum of beta-nickel 63 is considered as the total energy spectrum, average energy of the spectrum, and maximum spectral energy for analyzing the penetration depth of silicon. Monte Carlo calculations were carried out using a MCNPX code in a given geometry; in the following, Stopping-Power for electrons with different energies in silicon was calculated using the ESTAR computational code .The results are in good agreement. Also can be used in the design of semiconductor detectors and nuclear dosimeters.
