Collision of Incident Electrons with Liquid Water Molecules: Study of Linear Energy Transfer (LET)

Kane Issa, Aboubacar Almoustapha & OUSMANE MANGA Adamou · Asian Journal of Physical and Chemical Sciences · 2023

We used GAMOS software to simulate the interaction of electrons in liquid water. In our work, the chosen parameter, the Linear Energy Transfer (LET), is studied in an energy range from 2.5 eV to 100 MeV. The results obtained were analyzed and compared with experimental data and l...
