Spectroscopy of highly-ionized atoms using position-sensitive detection

We report new results of atomic structure and atomic lifetime measurements in highly-ionized few electron atoms obtained using position-sensitive detection of extreme ultraviolet emission from excited fast ions. Data is presented from experiments run at the Notre Dame Tandem Accelerator and at the Argonne ATLAS facility using beam-foil spectroscopy with a photon-counting position-sensitive imaging detector. The results include excited state lifetimes in Si XI and Si XII involving both resonance transitions and Rydberg transitions, spectra of high-ionized He-like, Li-like, and Be-like nickel including comparisons of electron capture and excitation processes for charge selected beams and spectra and lifetimes in highly-charged bromine ions for both allowed and forbidden transitions
