Definition: | the quotient of E by $\overline{N}$, where $\overline{N}$ is the mean number of ion pairs formed when the initial kinetic energy E of a charged particle is completely dissipated in the gas$W=\frac{E}{\overline{N}}$ NOTE – The ions produced by the bremsstrahlung emitted by the charged particle must be counted in $\overline{N}$. | ||
