Stopping Power Calculation of Protons using Bloch Correction and Semi Empirical Relation

Dr. Rashid Owaid Kadhim | Ahlam Habeeb Hussien

Abstract: One of the needs of various accelerators to stimulate recent developments in calculating the energy loss of charged particles in matter is heavy ion ionization energy loss. Bloch incorporates Bethe and Bohr theory in a very transparent way. Thus, Bloch found the bridging formulation between the classical Bohr impact parameter approach and the quantized Bethe momentum transfer approach to energy loss. In this paper, the behavior of Bloch correction of protons in (C_3 H_6, C_22 H_10 N_2 O_5) and for the energy range (0.1- 1000) MeV has been studied. We have described an implementation of Bloch correction to stopping power (dE dx) in order to take into account the deviations from the Bethe theory at non relativistic and relativistic velocities as well as the effects at ultra relativistic velocities. Bloch correction is expressed in terms of the transport cross section for electron ion scattering and dependence on the scattering phase shifts. Were calculated stopping power equation by quasi-experimental results showed using both methods showed good agreement with the results SRIM 2012.
