“…The values for seven levels belonging to 5p 4 6d configuration have been measured by Das and Bhattacharya [12]; one of the measurements are in strong disagreement with the value of Blagoev et al The τ (6p 4 P 5/2 ) was measured by Mitchell et al [13] using the cascade-photon-coincidence technique. Of particular interest is the work of Jullien et al [14] because that authors measured the transition probabilities of electric dipole-forbidden transition 2 P 1/2 → 2 P 3/2 and the corresponding τ ( 2 P 1/2 ).…”

In this work we make an experimental and theoretical investigation of transition probabilities (A) and lifetimes (τ ) of Xe II. Eighteen Aij's corresponding to the 6p-6d array were measured using a Laser Produced Plasma (LPP) as the spectroscopic source. The ab initio (AI) and Least Square Fitting (LSF) approaches were used to calculate the atomic parameters. Relativistic corrections and Configuration Interaction (CI) effects have been taken into account using the HFR approach described by Cowan. Whereas the AI parameters corresponding to 6p levels are not very affected by CI effects, several of the 6d levels with J = 1/2, 3/2 and 5/2 making transitions to the fundamental levels 5p 5 2 P 1/2,3/2 are affected by CI effects due to both, discrete nd and continuum d states, modifying their lifetimes values. An extensive comparison with other measurements and calculations are made. In particular, concerned with branching ratio and forbidden transitions.
