Radiative lifetimes, branching rations, and absolute transition probabilities in Cr II and Zn II

摘要: New absolute atomic transition probability measurements are reported for 12 transitions in Cr II and two Zn II. These probabilities determined by combining branching ratios measured classical techniques radiative lifetimes time-resolved laser-induced fluorescence. The compared with fractions, lifetimes, the literature. 206 nm resonance multiplets included this work. very useful determining distribution of elements gas versus grain phases interstellar medium.
