Ilford G-5 nuclear emulsion plates were exposed in vacuum to beams of He/ sup 4/, B/sup 10/, B/sup 11/, C/sup 12/, N/sup 14/, O/sup 16/ , F/sup 19/, and Ne/ sup 20/ ions. The ions were accelerated to about 10 Mev per amu, degraded to the desired energy by a variable thickness of metal foil or gas, and analyzed magnetically. Range-energy relations for these ions in dessicated G-5 emulsions were determined in this manner with an estimated accuracy of plus or minus 1%. Because the range-energy relations are intended for use in nuclear reaction experiments with machineaccelerated particles, no corrections were made for emulsion density. Comparison with similarly exposed llford emulsions of various different grain sizes and sensitivities in dicates no significant dependence of the range-energy relation on emulsion type. The track width was measured as a function of residual range for all ion species used. (auth)
