Monte Carlo dynamic transmission calculations for high energetic positrons implanted into a semi–crystalline polymer target film (Polytetrafluoroethylene)

Abstract :

In this work, backscattering and transmitted probability coefficients with mean penetrating depth has been calculated via Monte Carlo simulation technique PsMCS ( positronium Monte – Carlo Computer Simulation ) for positrons with different energies starting by high energies and finishing with very slow energy ( from 0.15MeV to 70 eV) ,implanted normally and with different angles , into a semi finite Polytetrafluoroethylene target ( PTFE ) . Comparison with available references yields good quantitative agreement for dynamics factors.
