Decays of metastable levels in the He-like ions Li+ and Be2+ were studied at a heavy-ion storage ring. The lifetimes involved span five orders of magnitude (from 0.5 ms to 50 s) and thus test the performance envelope of the experimental technique. Fo

The rates of several electric-dipole forbidden decays of 3p and 3d levels in Cl-, S-, P- and Si-like ions of Fe have been measured optically at a heavy-ion storage ring. In several cases, more than one decay contributes to a given decay curve, which

The radiative lifetime of the 2s2 2p4 1S0 level in Ne2+ ions has been measured by time-resolved observations of one of the electric-dipole forbidden decay branches, the magnetic dipole (M1) transition to the 2s2 2p4 3P1 level, on ions circulating in

The decay by magnetic dipole and electric quadrupole (M1 and E2) transitions of the 2s22p2 1D2 level in the ground complex of the C-like ion Si8+ and the 2s22p4 1D2 level in the O-like ion Si6+ have been optically observed with ions circulating in a

The decay rate of the 2s2 2p2 1S0 level in N II has been measured optically (λ = 575 nm) at a heavy-ion storage ring. The result of (1.10 ± 0.27) s-1 agrees with the theoretical predictions. The new data complement an earlier study of the same leve

New quasicrystalline phases in Ga85Mn15 and Al73Ni16Ta11 alloys have been formed by ion-beam mixing under specific irradiation conditions. These alloys are two of several predictions established on a systematic approach developed using the quantum st

Weak features have been observed in the spectra of foil-excited boron and carbon beams. They are attributed to radiative decay from the bound triply excited state 2p3 4S of the corresponding three-electron ion. In B III***, the wavelength observed fo

Bragg Gratings, Photosensitivity, and Poling in Glass Fibers and Waveguides: Applications and Fundamentals.
Thermal poling of silica offers the exciting prospect of achieving, for the first time, low-loss electro-optic switches and modulators in a fiber form, devices that can be fusion spliced to a single mode fiber with negligible loss, unlike any other e

The decay of the $4s4p^{1}P_{1}^{o}$ level in Krvii following beam-foil excitation has been simulated using theoretical initial-state populations and calculated transition probabilities. It was found that the decay curve was substantially influenced
