Transition Prabablities, Oscillator Strengths, Line Strengths, and lifetime of high-lying energy levels of singly ionized Helium (He II)

This Excel file (name: 35344 lines.xlsx) contains 9569 transition lines (in sheet name: 9569) for ns(2S 1/2), np(2P 1/2), and np(2P 3/2) series of He II. The lifetimes of 176 levels from series ns(2S 1/2), np(2P 1/2), and np(2P 3/2) are determined from all transition channels of 9569 lines. Another dataset in the same file (sheet name: 25775) has 25775 lines up to n=43 for orbitals s,p,d,f,g,h,i,k. The lifetimes of 509 levels are estimated too.
