Executive Summary : | Recent years have seen a significant focus on studying the structural properties and radiative transition properties of highly charged ions in a strongly coupled plasma environment. This understanding has potential applications in inertial confinement fusion, X-ray lasers, laser produced plasma, plasma spectroscopy, and astrophysical systems. The interaction of atoms and ions in high density plasma environments can alter electronic structures, leading to broadening of spectral lines, shift of emission lines, ionization potential depression, and continuum lowering compared to free ions. X-ray free electron lasers and high-energy optical lasers enable the creation of matter in plasma form and studying it under extreme conditions like high temperature and density. The effect of the external electric field on plasma-embedded atoms and ions has also gained attention. The magnetic field and plasma shielding effects on the spectrum of astrophysical useful hydrogen, helium, and carbon ions in dense magnetized plasmas are also under investigation. Reliable atomic data are needed for estimating physical conditions, investigating highly stripped impurity ions, and advancements in other fields like ultraviolet (UV) and X-ray lithography, and producing X-ray lasers. The required atomic data can be in the form of transition energies, radiative data for allowed and forbidden transitions, photoionization, and electron impact excitation cross sections. |
