| Abstract | : | Calculated energy loss (straggling, Landau) functions are compared with the ionization spectra for ions measured in the STAR TPC. The useful descriptors for these functions are the most probable energy loss Delta p and the full-width-at-half maximum w. Experimental and calculated functions agree well for most of the measurements included in this study. Comparisions between theory and experiment can provide information about the purity of a selected spectrum and about various problems in the TPC. Also, the theory can lead to better discrimination for dE/dx particle identification. |
