Abstract:
We present our calculated data including energy levels and lifetimes
(in table1), radiative rates, oscillator strengths and line strengths
(in table2), collision strengths (in table3), and effective collision
strengths (in table4) for all the transitions among 36 fine-structure
levels from n≤6 configurations in H-like ions with 13≤Z≤42.
Description:
Files table1 and table2 report energy levels and lifetimes (in
table1), radiative rates, oscillator strengths and line strengths (in
table2), those data are obtained via relativistic configuration
interaction method. File table3 reports collision strengths obtained
via relativistic distorded wave method. File table4 reports effective
collision strengths calculated using the isolated process and isolated
resonances approximation.
