Extreme-ultraviolet (EUV) spectra of Sn 13+− Sn 15+ ions have been measured in an
electron-beam ion trap (EBIT). A matrix inversion method is employed to unravel convoluted …

We experimentally re-evaluate the fine structure of Sn 11+–Sn 14+ ions. These ions are
essential in bright extreme-ultraviolet (EUV) plasma-light sources for next-generation …

We analyze the complex level structure of ions with many-valence-electron open-[Kr] 4 dm
subshells (m= 7–4) with ab initio calculations based on configuration-interaction many-body …

Theoretical extreme ultraviolet emission spectra of gadolinium and terbium ions calculated
with the Cowan suite of codes and the flexible atomic code (FAC) relativistic code are …

Extreme ultraviolet emission spectra of multiply charged Sn ions were measured in the
wavelength range 5–38 nm, following electron capture into the excited states of slow Sn …

We have begun a preliminary investigation into the opacity of Sn at low temperatures (< 50
eV). The emissivity and opacity of Sn is a crucial factor in determining the utility of Sn in EUV …

Radiative opacity and emissivity of tin plasmas at average ionization degree of about 10 was
investigated in detail by using a fully relativistic detailed level accounting approach, in which …

The energy levels, wavelengths, oscillator strengths, and radiative electric dipole (E1),
magnetic quadrupole (M2) transition probabilities for Ge-like ions (49≤ Z≤ 58) among the …

Energy levels, wavefunction compositions, and lifetimes are computed for all levels of
4s24p5, 4s24p44d, and 4s4p6 configurations in Br-like ions (Z= 47–50). We use the …

Energy levels, wavelengths, transition probabilities, and oscillator strengths have been
calculated for Ge-like Kr, Mo, Sn, and Xe ions among the fine-structure levels of terms …
