A SOFTWARE FOR THE CALCULATION OF ION-TRANSPORT IN SOLIDS

Based on the bipartition model of ion transport, a software, named PAN DA-U, has been established for calculations of ion transport in solids . This software is designed running on the platform of WIN32. By PANDA -U, one can calculate reflection, range, radiation damage etc, for ion bombardments on multilayer targets. In PANDA-U, the distribution func tion of ions is stored in a module which could be accessed by user, th us one can develop more applications to calculate other concerned tran sport quantities. As an example of PANDA-U, we have calculated reflect ion energy spectrum at emission angle of 45 degrees for 150 eV H bomba rdment on C. By comparing the results with Monte Carlo data and experi mental data, the validity of our calculation has been tested. (C) 1998 Elsevier Science B.V.
