Abstract

Lifetime measurements using beam foil techniques for the $5 s 5 p^{2}$ $^{2} D_{3/2, 5/2}$ levels in Sn II are presented. The resulting oscillator strengths for transitions at 1699.4, 1831.8 and 1811.2 Å are reported. We also studied these levels with multi-configuration Dirac Hartree-Fock (MCDHF) calculations using a development version of the GRASP2K package. Our experimental and theoretical results are compared with other available studies.
