Experimental radiative lifetimes, branching fractions, transition probabilities and oscillator strengths of some levels in Au I

Abstract

Radiative lifetimes of ten odd-parity levels in neutral gold were measured by time-resolved laser-induced fluorescence method, and six of them were reported for the first time. Branching fractions (BFs) of 15 lines for eight of these levels were determined by the emission spectrum of a hollow cathode lamp. The transition probabilities and oscillator strengths of these lines were derived by combining the BFs with lifetime values. The lifetime and oscillator strength results are in very good agreement with previous data.
