Stopping of Slow Hydrogen Dicluster by Different Solid Materials

Mohammed Abdu-Hamza Akraa, Khalid A. Ahmed, Iman T. Al-Alawy


In this theoretical work, the subject of stopping power is investigated for slow hydrogen dicluster by using random phase approximation. The projectile is stopped by variance solids of different Wigner Seitz radiuses. The considered stopping power is related to the interaction between a low velocity dicluster  of zero damping interacts with (Au, C, Al, and Cs) targets mediums based on an electron gas model.The subject of an ionic dicluster stopping power has been calculated by using Random Phase Approximation (RPA) at low velocity for the first and second approximation order, where the influence of damping has been ignored. The obtained results of this study show detailed behavior of the ionic dicluster of its duality interaction with several electron density targets mediums of long range collision belongs to aggregation effect, their affected parameters as internuclear distance of dicluster, and its velocity are studied.The results have been achieved by using programs of Fortran-90 language which performed for the numerical calculation.
