The branching ratio of intercombination $A^{1} Σ^{+} \sim b^{3} Π \to a^{3} Σ^{+} / X^{1} Σ^{+}$ transitions in the RbCs molecule: measurements and calculations

Valts Krumins, Artis Kruzins, Maris Tamanis +6

We observed the $A^{1} Σ^{+} \sim b^{3} Π \to a^{3} Σ^{+} / X^{1} Σ^{+}$ laser-induced fluorescence (LIF) spectra of the RbCs molecule excited from the ground $X^{1} Σ^{+}$ state by the Ti:Sapphire laser. Th…

Diagonal and off-diagonal hyperfine structure matrix elements in KCs within the relativistic Fock space coupled cluster theory

Alexander V. Oleynichenko, Leonid V. Skripnikov, Andrei Zaitsevskii +2

The four-component relativistic Fock space coupled cluster method is used to describe the magnetic hyperfine interaction in low-lying electronic states of the KCs molecule. Both di…

Fourier transform spectroscopy, relativistic electronic structure calculation, and coupled-channel deperturbation analysis of the fully mixed $A^{1} Σ_{u}^{+}$ and $b^{3} Π_{u}$ states of Cs $_{2}$

A. Znotins, A. Kruzins, M. Tamanis +4

The 4503 rovibronic term values belonging to the mutually perturbed $A^{1} Σ_{u}^{+}$ and $b^{3} Π_{u}$ states of Cs $_{2}$ were extracted from laser induced fluorescence (LIF) $A\sim b\rightarro…

Adsorption of the astatine species on gold surface: a relativistic density functional theory study

Yuriy Demidov, Andrei Zaitsevskii

We report on first-principle based studies of the adsorption interaction of astatine species on a gold surface. These studies are aimed primarily at the support and interpretation…

The generalized relativistic effective core potential calculations of the adiabatic potential curve and spectroscopic constants for the ground electronic state of the Ca2

N. S. Mosyagin, A. N. Petrov, A. V. Titov +1

The potential curve, dissociation energy, equilibrium internuclear distance, and spectroscopic constants for the ground state of the Ca2 molecule are calculated with the help of th…
