Motion of Rydberg atoms induced by resonant dipole-dipole interactions
C. Ates, A. Eisfeld, J. M. Rost
We show that nuclear motion of Rydberg atoms can be induced by resonant dipole-dipole interactions that trigger the energy transfer between two energetically close Rydberg states.…
Nuclear deformation effect on the binding energies in heavy ions
Y. S. Kozhedub, O. V. Andreev, V. M. Shabaev +5
Nuclear deformation effects on the binding energies in heavy ions are investigated. Approximate formulas for the nuclear-size correction and the isotope shift for deformed nuclei a…
Initial state dependence in multi-electron threshold ionization of atoms
Agapi Emmanouilidou, Peijie Wang, Jan Michael Rost
It is shown that the geometry of multi-electron threshold ionization in atoms depends on the initial configuration of bound electrons. The reason for this behavior is found in the…
Relativistic calculations of the lifetimes and hyperfine structure constants in Zn
Gopal Dixit, H. S. Nataraj, B. K. Sahoo +2
This work presents accurate {\it ab initio} determination of the magnetic dipole (M1) and electric quadrupole (E2) hyperfine structure constants for the ground and a few low-lying…
Theoretical spectroscopic studies of the atomic transitions and lifetimes of low-lying states in Ti IV
Subhasish Mandal, Gopal Dixit, B. K. Sahoo +2
The astrophysically important electric quadrupole (E2) and magnetic dipole (M1) transitions for the low-lying states of triply ionized titanium (Ti IV) are calculated very accurate…
The electron electric dipole moment enhancement factors of Rubidium and Caesium atoms
H. S. Nataraj, B. K. Sahoo, B. P. Das +2
The enhancement factors of the electric dipole moment (EDM) of the ground states of two paramagnetic atoms; rubidium (Rb) and caesium (Cs) which are sensitive to the electron EDM a…
Ab initio relativistic many-body calculation of hyperfine splitting of ^{113}Cd^+
Gopal Dixit, H. S. Nataraj, B. K. Sahoo +2
This work presents accurate ab initio determination of the hyperfine splitting for the ground state and few low-lying excited states of 113Cd+; important candidates for the frequen…
Investigations of Ra properties to test possibilities of new optical frequency standards
B. K. Sahoo, B. P. Das, R. K. Chaudhuri +3
The present work tests the suitability of the narrow transitions and in Ra for optical frequency standard stud…
Many-body theory of excitation dynamics in an ultracold Rydberg gas
Cenap Ates, Thomas Pohl, Thomas Pattard +1
We develop a theoretical approach for the dynamics of Rydberg excitations in ultracold gases, with a realistically large number of atoms. We rely on the reduction of the single-ato…
Single photoeffect on helium-like ions in the non-relativistic region
A. I. Mikhailov, A. V. Nefiodov, G. Plunien
We present a generalization of the pioneering results obtained for single K-shell photoionization of H-like ions by M. Stobbe [Ann. Phys. 7 (1930) 661] to the case of the helium is…
{\it Ab initio} calculations of forbidden transition probabilities and lifetimes of low-lying states in V
Gopal Dixit, B. K. Sahoo, P. C. Deshmukh +2
Electric quadrupole (E2) and magnetic dipole (M1) transition amplitudes among the low-lying states of quadruply ionized vanadium V, important in various field of experimenta…
Accurate estimations of circumstellar and interstellar lines of quadruply ionized vanadium using the coupled cluster approach
Gopal Dixit, B. K. Sahoo, P. C. Deshmukh +2
Accurate {\it ab initio} calculations have been carried out to study the valence electron removal energies and oscillator strengths of astrophysically important electromagnetic tra…
