We performed an axi-symmetric, two-dimensional experiment on the high-explosive LX-14. We used low-energy X-rays to image the detonation front at multiple times. The experiment provides a stringent test of radiographic unfolding techniques and has th

High precision measurements of two Zeeman hyperfine transitions in the ground state of muonium in a strong magnetic field have been made at LAMPF using microwave magnetic resonance spectroscopy and a resonance line narrowing technique. These determin

The spectroscopy of very highly ionized atoms provides an important testing ground for multielectron atomic theory. We report preliminary experimental results on the n = 3 → 2 spectra of Bi73+ and Au69+ obtained at the GSI UNILAC accelerator.

The positronium n = 1 fine-structure interval, Δ v , has been measured in nitrogen yielding Δv = 203.3849(12) GHz. Comparison with theory shows the need to calculate higher-order theoretical terms. The positronium density shifts in the noble gases

The spectrum of neonlike gold (+69) is observed in a beam-foil light source utilizing an x-ray crystal spectrograph. Precision wavelength determinations indicate variations from multi- configurational Dirac-Fock calculations for states sampling the 2
