Abstract
Solving certain problems in various fields of science and technology requires knowledge of certain characteristics of atoms and molecules. These characteristics include the energy and radiation parameters of these particles. In this regard, it is necessary to create a database of reference data that, firstly, is regularly updated, and, secondly, would be available to various specialists (for example, designers, engineers, scientists, etc.) working in such fields as chemical thermodynamics and kinetics, atomic and molecular physics, gas and radiation dynamics, quantum electronics and chemistry, etc. The article calculates the values of energy and radiation parameters: Frank --- Condon factors and Einstein coefficients, oscillatory energies and oscillator forces, wave numbers of electron-vibrational transitions in the system of A1Σu+ -- X1Σg+ bands of a strontium dimer molecular particle. The calculations are based on the constructed potential curves of the perturbed Morse oscillator. The calculated radiation parameters of the strontium dimer electron transition A1Σu+ -- X1Σg+ have been obtained for the first time, so they are very relevant for updating the reference databases. The values of the calculated Frank --- Condon factors, Einstein coefficients, and wavenumbers of the oscillating bands can be used to create gas lasers
