The analysis of the vacuum spark spectrum of erbium in the wavelength region 705 - 2460 A has been extended. A total of 1022 spectral lines are newly identified as transitions between the low lying configurations 4 f 11 , 4 f 10 5 d , 4 f 10 6 s and

We characterize the anisotropic differential ac-Stark shift for the Dy $626$ nm intercombination transition, induced in a far-detuned $1070$ nm optical dipole trap, and observe the existence of a "magic polarization" for which the polarizabilities of

The spectra of osmium and iridium were photographed in the 300 Å to 1600 Å region on a 3 m normal incidence spectrograph using a triggered spark source. The (5d2 + 5d6s)–5d6p transition arrays of Os VII and Ir VIII were analyzed. All levels of th

The efficiency of optical trapping of ultracold atoms depend on the atomic dynamic dipole polarizability governing the atom-field interaction. In this article, we have calculated the real and imaginary parts of the dynamic dipole polarizability of dy
