A new software for calculating the differential scattering parameters for radiation applications: DSPCal

This study aimed to develop a new software tool, called Differential Scattering Parameters Calculator (DSPCal), to calculate differential scattering parameters for a wide range of materials, spanning various energies and scattering angles. The program was developed to calculate differential cross sections and total molecular mass differential scattering coefficients (TMMDSC). The objective was to provide a user-friendly tool to easily determine the TMMDSC at any desired energy and angle in the continuous photon energy, scattering angle or momentum transfer region. The DSPCal program was developed using the Python programming language and employs the principles of differential scattering parameters. The program was tested on different materials and showed good agreement with the available literature results. Specifically, for compounds like Water, Glycerol and Fe2O3, the differences between program results and other results from the literature were found to be ≤ 0.00%, ≤ 0.00% and ≤ 0.86% respectively. These results indicate that the program is reliable and accurate in calculating the differential scattering parameters for a wide range of materials. The program is available for free and can be useful in various fields that utilize nuclear radiation for different purposes, including diagnostic, therapeutic, imaging, and materials design for radiation shielding. The accuracy and reliability of the program were demonstrated through comparisons with available literature results, indicating its potential as a valuable tool for researchers in the field of nuclear radiation. The source code of DSPCal will be maintained at.
