Calculation of Polarizabilities for Atoms with Open Shells [PDF]
Symmetry, 2020 A version of the configuration interaction method for atoms with open shells (the Configuration Interaction with Perturbation Theory—CIPT method, PRA 95, 012503 (2017)) is extended for calculation of static and dynamic polarizabilities. Its use is demonstrated by calculation of the polarizabilities for the ground and excited states of Er, Tm and Yb. It

Application of Symmetry-Adapted Atomic Amplitudes
Atoms, 2022 Following the work of Giulio Racah and others from the 1940s onward, the rotational symmetry of atoms and ions, e.g., the conservation of angular momentum, has been utilized in order to efficiently predict atomic behavior, from their level structure to ...

Atomic ionization at positron annihilation at β+-decay with taking into account screening [PDF]
Ядерна фізика та енергетика, 2012 The role of the nuclear charge screening and correctness of Born approximation for electron which is leaving atom in the process of atomic ionization at annihilation of positron with another electron of daughter's atom at β+-decay is studied. Processes

Level Structure and Properties of Open f-Shell Elements
Atoms, 2022 Open f-shell elements still constitute a great challenge for atomic theory owing to their (very) rich fine-structure and strong correlations among the valence-shell electrons.

Atomic shell ionization and e+e−-pairs creation at the finite nuclear temperatures [PDF]
Ядерна фізика та енергетика, 2009 General expressions for the probabilities of the atomic shell ionization and e+e- -pairs creation at the “heated” nuclei are found. The spectral distributions of the positrons and conversion electrons are investigated in the case of the nuclear E1 ...

Positron elastic scattering by a semifilled-shell atom* [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2021 Abstract We theoretically study the positron elastic scattering by an atom with a multielectron semifilled subshell in its structure. We focus on gaining the initial insight into the specifics of such a process.

Test of internal-conversion theory with a measurement in 111Cd
EPJ Web of Conferences, 2017 We have measured the K-shell and total internal conversion coefficients for the 150.8-keV E3 transition in 111Cd: αK = 1.449(18) and αT = 2.217(26) respectively.
