Abstract
We measured the spontaneous-emission branching fractions of 46 levels in Nd II, selectively populated via single-frequency laser excitation of a 10 keV ion beam. The levels studied had term energies up to 29 955 cm–1, and decay branches with spontaneous emission in the range 372–850 nm were detected. The experimental accuracy for branching fractions over 0.1 was ~7%. We used these branching fractions along with our previously determined radiative lifetimes to infer transition probabilities and oscillator strengths for 430 transitions, which are useful for stellar abundance determinations.
