Calculations of Stopping Powers for Electron in Bio-molecules

Accurate information for the stopping powers (\textbf{SP}s) of various media including various complicated molecules for energetic electrons becomes essential in many areas of current research including health sciences. Few easy to implement formulas have enjoyed much use for atomic targets [1]. Molecular media, especially the bio-molecules, poses stringent test of any available relied theories. A semi empirical model including the accurate density distributions of the media is proposed to investigate complex molecular targets; our calculated \textbf{SP}s for \textbf{H}$_{2}$\textbf{O and C}$_{\mathbf{5}}$\textbf{H}$_{\mathbf{5}}$\textbf{N}$_{\mathbf{5}}$\textbf{O }are found in good agreement with available experimental findings for E $=$1 to 10 GeV region. \\[4pt] [1] A.
