(Lithium), Na (Sodium) and N (Nitrojen) atoms were calculated by using Slater Type Orbitals (STOs) and
Gaussian Type Orbitals (GTOs) in accordance with the electric dipole approximation. For the calculations
based on STO type orbitals analytic expressions were obtained for the spontaneous transition probabilities
within the single electron atom approximation. Although obtained analytical expressions were extended to
include many electron atoms, LS coupling among electrons and configuration interaction effects were not
taken into consideration. A computer program was written in C programming language by using these
analytical expressions and the calculations for STO type orbitals were performed by using this program.
Also similar calculations were performed using the Gaussian-98 software in which GTO basis functions are
employed. However, in the calculations with Gaussian-98 we have used CIS method which takes single
configuration interactions into account. The results obtained from the calculations with STO and GTO basis
sets were compared with each other and the values obtained from the literature. Considering these results,
the differences between different calculation methods and different basis sets were discussed.}, number={3}
