Description:
Oscillator strengths calculated for 101 lines of Sn II arising from
auto-ionized levels are displayed in column three of Table A1, while
columns one and two give the transitions and corresponding
wavelengths, respectively.
In the second column of Table A2, we present the radiative lifetimes
calculated for 13 levels of Sn II.
Two levels correspond to 5s2 4f 2F5/2 5s2 4f 2F7/2 for both
theoretical and experimental values obtained by other authors. In the
other columns of Table 2 we present these values. A good agreement
exists between our work and the experimental values.
The eleven remaining values correspond to the levels labeled by Moore
as 1° at 11° and whose identification is based on the IC
5p3-5s5p5d-5s5p6s.
