摘要
Ranges of some heavy ions of initial energies of up to 10 MeV per nucleon in some complex media (Mylar, polyethylene, tissue - material, and G-5 nuclear emulsion) and in some elemental media (oxygen, nitrogen, argon, nickel and silver) have been computed on the basis of a set of stopping-power equations deduced from a basic stopping-power equation of Bohr. In the present work we have revised the earlier stopping-power equations of Mukherji and Srivastava and the formula of Mukherji for the calculation of the mean ionization potentials of the elements. The calculated ranges in Mylar, polyethylene, tissue-matter and in the elemental media are in excellent agreement with the available experimental data. In G-5 nuclear emulsion, the calculated ranges are higher than the experimental ones at the lower energies but agreement is good at the higher energies except in the case of 20Ne ion. © 1979.
