Comparative characteristics of tax revenues in the budget of the Republic of Crimea. The model of competitiveness of tourist field. Calculated the competitiveness of enterprises of the tourism sector matrix method.
We have applied the full-relativistic Dirac B-Spline R-matrix method to obtain cross sections for electron scattering from ytterbium atoms. The results are compared with those obtained from a semi-relativistic (Breit-Pauli) model-potential approach and the few available experimental data.
