ResumoThe energy deposited in a 94.6-\ensuremath{\mu}m-thick totally depleted silicon detector by beams of $^{3}\mathrm{He}$ and $^{4}\mathrm{He}$ ions was measured at incident energies up to 10 MeV/amu. It is assumed that the stopping power of an ion of energy $E$, mass $M$, and charge $z$ can be expressed approximately by $S=A{[(\frac{E}{M})+r]}^{1\ensuremath{-}n}$, and the parameters $A$, $n$, and $r$ are determined from the energy-loss data. Within the experimental error the results are found to agree with recent theoretical calculations which include a ${z}^{3}$ correction.
