AI Article Synopsis
- A new semiempirical model has been developed to calculate electron emission from organic compounds when they are hit by ions, requiring only the target's density and composition as inputs.
- The model has demonstrated strong agreement with experimental data, specifically for protons hitting key biological targets like water and DNA components.
- Due to its simplicity and accuracy, this model can be easily applied to different biological targets and charged particles, making it useful for ion beam cancer therapy.
Article Abstract
We present a semiempirical model for calculating the electron emission from any organic compound after ion impact. With only the input of the density and composition of the target we are able to evaluate its ionization cross sections using plausible approximations. Results for protons impacting in the most representative biological targets (such as water or DNA components) show a very good comparison with experimental data. Because of its simplicity and great predictive effectiveness, the method can be immediately extended to any combination of biological target and charged particle of interest in ion beam cancer therapy.
