Perekhod O. The system of the solar oscillator strengths of selected spectral lines

Object of investigations: The oscillator strengths of spectral lines. Aim of investigation: Elaboration and using of the semiempirical technique to determining the oscillator strengths of spectral lines which are weak and/or greatly blended in the solar spectrum. Methods: The solar spectrum modelling. Results: The oscillator strengths of 77 spectral lines of 18 chemical elements (and 33 - for Ca I) have been determined. The upper limit of technetium abundance in the solar atmosphere was acquired. Int roduction: The results are used in the astronomil observatories for the chemical abundance determining in stellar atmospheres. Applications: The quantitative spectral analysis.
