Abstract
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 are reported. Data are 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 highly-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.
