Studies of Lanthanides 6s Ionization Energy
G. Gaigalas, Z. Rudzikas, T. Zalandauskas
This work is aimed at the multi-configuration Hartree-Fock calculations of the 6s ionization energies of lanthanides with configurations [Xe]4f^{N}6s^{2}. Authors have used the ATS…
Integration over spin-angular variables in atomic physics
G. Gaigalas
A review of methods for finding general expressions for matrix elements (non-diagonal with respect to configurations included) of any one- and two-particle operator for an arbitrar…
Secondly quantized multi-configurational approach for atomic databases
G. Gaigalas, Z. Rudzikas
General method is suggested to find non-relativistic and relativistic matrix elements of one- and two-electron operators for any number of open shells in atom, requiring neither co…
The library of subroutines for calculation of matrix elements of two-particle operators for many-electron atoms
G. Gaigalas
In this paper a library for spin--angular integration in LS-coupling for many-electron atoms is presented. The software is an implementation of a methodology based on the second qu…
The library of subroutines for calculating standard quantities in atomic structure theory
G. Gaigalas
This library (collection of subroutines) is presented for calculating standard quantities in the decomposition of many-electron matrix elements in atomic structure theory. These qu…
Some new simplifications for general form of the orbit-orbit interaction operator
G. Gaigalas
The general tensorial form of the orbit-orbit interaction operator in the formalism of second quantization is presented. Such an expression is needed to calculate both diagonal and…
