Contribution of Outer Electron and Inner-Shell Electron to Proton Energy Loss in Liquid Water and DNA

Full Text PDF


In the present work Drude-dielectric formalism has been used to calculate the effects of contribution of inner and outer-electron shell to energy-loss of protons liquid water H2O and DNA. The results show that the incident protons with energy between (T = 0.05, 0.25, 1, 2, 2.5 MeV) are very efficient in producing secondary electrons in dry DNA, which are able to produce strand breaks and could be very effective for the biological damage of malignant cells. The PSPEC, Stopping power, average energy transfer, ∆E and ionization energy have been calculated taking in the consideration the Sub-shells of each elements in DNA and H2O, Fourier energy density ρ (q), Charge exchange and Screening effects ᴧ. Good agreement achieved with the previous work [1].
