Higher order moments associated with energy loss distribution of swift heavy ions in thick polyethylene napthalate polymeric foils

In continuation to our earlier studies related to energy loss and associated straggling for swift heavy ions which are generally considered as first and second order moments, respectively, in the present study, we have developed a method for the determination of skewness (third-order moment) in the energy loss distribution of the transmitted ions. In this article, the results of our measurements and their interpretation related to skewness for swift heavy ions covering Z=6−16 with maximum values of fractional energy loss (Δ E/E) upto 75% in polyethylene napthalate polymeric foils have been presented.
