| Research Abstract |
There are few experimental data for W for heavy ion and that is one of indefinite parameters in dose evaluation or in presumption of absorbed energy . We aim to determine W for heavy ions as a function of energy, to provide data to application fields such as the heavy ion therapy , and to explicate mechanisms of the dependence. In this study , we measured W and the differential values of W (w)for He2+, C6+, N7+, O8+, Si14+, Ar18+and Fe26+, and the clear dependence of energy was observed in lower energy of less than 3MeV/n.
