Abstract:
The energy-loss (straggling) of Zirconia (ZrO2) and alumina (Al2O3) have been determined theoretically for proton and alpha-particle beams with incident energies (T= 0.05, 0.25, 1, 2, 2.5) (Mev/u). The dielectric formalism like Plasmon Pole Approximation (PPA) has been used to calculate the probability for an energetic proton and alpha to produce electronic excitations in target of Zirconia (ZrO2) and alumina (Al2O3), taking in the consideration screening length effects.Good agreement is achieved with previous work using Gaussian and Simpsons rule for numerical calculations in the program
