Experimental studies of the slowing down of 1H, 4He, 7Li, 11B, 12C, 14N, and 16O ions in LR-115 type II cellulose nitrate nuclear track etch material in the ion energy range 0.3-4.3 MeV amu-1 are presented. The ion stopping powers obtained are compared with the predictions of two recent semi-empirical models for calculating ion stopping powers. The predictions are found to underestimate the observed stopping powers for 7Li, 11B and 12C ions. The deviations are below 10%. The stopping power data are further compared with those of a polypyromellitimide material (Kapton) composed of the same atomic elements. The similar stopping power behaviour observed for these two materials, in agreement with semi-empirical predictions, is discussed.
