By using a distorted-wave Born exchange ( DWBE ) approximation method including the relativistic correction, we calculated the direct ionization and excitation autoionization cross sections of eight Na-like ions. Based on the calculated results, we present two empirical formulas with high accuracy for calculating direct ionization and excitation autoionization cross sections. Our results are in good agreement with the experiment data and other theoretical values.
