An analysis of the power law type algorithm for identification of heavy ions by using the modified Zaidins empirical range-energy relationship

The properties of the power law type particle identification formula are studied as a function of the detector thickness. The result shows that the formula is applicable to energies lower than one could expect from the deviations of the power law of the range-energy relationship for heavy ions. For this analysis, the empirical range-energy formula proposed by Zaidins has been improved in order to obtain a better estimate of the range, especially for heavy ions. Experimental results of heavy ion identification thus obtained are also shown. (Auth.)
