Atomic Transition Probabilities in Ti <scp>i</scp>

Abstract

We report the measurement of 92 branching fractions and atomic transition probabilities in Ti I. High-current, hollow cathode spectra recorded using the Fourier transform spectrometer at the National Solar Observatory are used to determine the branching fractions. An absolute scale is established using recently reported radiative lifetimes from time-resolved laser induced uorescence measurements. These 92 lines are connected to high-lying, even parity levels in neutral Ti. Most of our transition probabilities are accurate to better than ^10%.
