Lifetime measurements and transition probabilities in Mo II

Lifetimes have been measured using time-resolved laser-induced fluorescence for 16 odd levels in the doublet, quartet and sextet systems of Mo II, with energies in the range 48 000– 61 000 cm−1. Absolute transition probabilities and oscillator strengths are determined for 110 UV and visible transitions (208 < λ < 485 nm) from a combination of experimental lifetimes and theoretical branching fractions. The theoretical results are obtained using the HFR method including core polarization effects.
