Abstract

Radiative lifetimes measured by time-resolved laser-induced fluorescence are reported for 40 odd-parity levels and 36 even-parity levels of singly ionized terbium. The odd-parity levels range in energy from 29 000 to 40 000 cm-1 and those of even-parity from 21 000 to 37 000 cm-1. These lifetimes, with one exception, are accurate to ±5%. They will provide an absolute scale for accurate atomic-transition probabilities in Tb ii (the second spectrum of terbium).
