Highly charged ions

WebHigh temperatures or intense photon fluxes create highly charged ions in astrophysical plasmas. The atomic properties of these ions determine heating and cooling rates and opacities. The intensities of X-ray and ultraviolet spectral lines provide diagnostics for plasma temperature, density, ionization state and elemental composition. WebThe study of highly charged ions involves various branches of physics. It was the aim of the conference to bring together physicists working in atomic collisions and spectroscopy, in plasma physics and astrophysics, as well as in solid-state and ion-source physics. About 220 scientists from 20 nations attended the conference, indicating the ...
