Abstract

The range of heavy ions in compounds is fitted with power equation form which gaves good agreement with previous work of SRIM[13] by Ziegler taking in the consideration effective charge and nuclear stopping cross-section (i) from Lindhard and (ii) from Sorensen. The coefficients of range have been calculated numerically using least square method [LSM]. Through the investigation of present work, especially when taking the effective charge in the consideration the stopping cross-section is not directly proportional to the velocity at as presented by Lindhard has different form of curvature according to previous experimental data. Good agreement achieved with previous work of software SRIM presented by Ziegler [13]. More work needs to do with the range of heavy ions in compounds.
