Abstract
We have measured radiative lifetimes of 35 levels of Nd II using the collin ear beam-laser method. The levels studied had term energies up to similar t o 30 000 cm(-1) and lifetimes of 10 to 100 ns. Experimental accuracy was in the range 1.5-14%. These measurements are a first step to providing new an d updated oscillator strengths needed for abundance determinations from ste llar spectra.
