We consider a narrow magneto-dipole transition in the Tm 169 atom at the wavelength of
1.14 μ m as a candidate for a two-dimensional-optical lattice clock. Calculating dynamic …

In the present study, we investigate the effect of Debye-Hückel potentials on the frequency-
dependent dipole polarizability of the helium atom using highly correlated wave functions …

We present a semiempirical analytical model for the static polarizability of electronically
excited atoms and molecules, which requires very few readily accessible input data …

The dynamic dipole polarizabilities for the four lowest triplet states (2 3 S, 3 3 S, 2 3 P, and 3
3 P) of helium are calculated using the B-spline configuration interaction method. Present …

Context. Compared with the visible and ultraviolet ranges, fewer atomic and ionic lines are
available in the infrared spectral region. Atlases of stellar spectra often provide only a short …

The effects of weakly coupled plasmas on the dynamic dipole polarizabilities of the H− and
Ps− ions are investigated using highly correlated exponential wave functions. The Debye …

The effects of Debye plasma on the frequency‐dependent polarizabilities of Li and Na atoms
are investigated using symplectic algorithm within the framework of the pseudostate …

We study spectra of a plasma created by the laser ablation of ZnS targets in a vacuum and
report 47 (not observed previously) Zn I lines in the range of 1300–6400 cm− 1. From the …

We investigate the effect of plasma screening on the tune-out wavelengths for helium atom
using correlated exponential wave function within the framework of Debye shielding …

The Green function in the quantum defect theory provides an exact account for the high-
excited and continuum electronic states. We modify it by taking into account the ground and …
