Theoretical energy levels and energy-level separations for n= 1 and n= 2 states of hydrogen-
like atoms with nuclear charge numbers in the range 1⩽ Z⩽ 110 are tabulated. Quantum …

Based on recent findings that the variation of charge fractions, mean charges, and charge
distribution widths with ion energy E and projectile atomic number Z is strongly dependent …

In this Report work on subbarrier fusion of atomic nuclei carried out during the past few
years is reviewed. We begin by outlining the techniques developed to measure the rare …

The application of the slowing-down process of relativistic heavy ions in a layer of matter in
ion-optical devices is theoretically investigated. The modifications of the phase space of the …

Modern experimental and theoretical methods to investigate multicharged ion spectra are
reviewed, including the study of radiation and cooperative electron-nuclear effects. A …

A high‐current ion source is described in which a metal vapor vacuum arc is used to create
the plasma from which the ion beam is extracted. An ion beam current of up to about 1 A has …

Cross sections for the electron capture by 82-, 140-, and 200-MeV/amu Xe 5 4+, Xe 5 3+,
and Xe 5 2+ ions incident on thin solid targets from Be to Au were measured. The …

X-ray studies of relativistic heavy-ion-atom collisions allow the direct observation of the
radiative-electron-capture photons. The angular distribution of these photons is …

Abstract The n= 2→ n= 1 lines of hydrogenlike and heliumlike uranium have been observed
and are being reported for the first time. The spectrum consists of all allowed and forbidden …

We report a value of 70.4±8.3 eV for the one-electron Lamb shift in uranium, in agreement
with the theoretical value of 75.3±0.4 eV. We extract our Lamb shift from a beam-foil time-of …
