Stark broadening of ${\mathrm{H}}_{\alpha }$ and ${\mathrm{H}}_{\beta }$ lines of ${\mathrm{C}}^{5+}$

We have computed the Stark-broadened profiles of the first two Balmer lines ($n=3,4\mathrm{}\to 2$) of ${\mathrm{C}}^{5+}$. Plasma conditions span the electron density range $n_e={10}^{17}-{10}^{20}$ ${\mathrm{cm}}^{-3\mathrm{}}$, and $T=20\mathrm{}-300$ eV. The calculations include ion-dynamic effects, which we find are very important at the lower densities for ${\mathrm{H}}_{\alpha }(n=3\mathrm{}\to 2)$. At the higher densities, the dynamic profiles approach the static ones.
