On the Establishment of Internally Consistent Solar Scales of Oscillator Strengths and Abundances of Chemical Elements - Part Two - on the Errors of the Oscillator Strengths of FEI Lines in the Kurucz
Abstract
It is shown that the errors on the oscillator strengths of the Kurucz-Peytremann gf-scale depend in a regular way upon the excitation potential and gf-value. Oscillator strengths with small values of gf and large excitation potentials are underestimated, and vice versa. Especially strong underestimations (by ≈2 orders of magnitude) of the oscillator strengths take place for the lines with excitation potentials EPL > 4 eV and oscillator strengths log gf < -4.0.
