Photoelectron spectra of cold Ti-n(-) anion clusters for n=1-130 were investigated at four detachment photon energies: 532, 355, 266, and 193 nm. Improved spectral resolution provides well-resolved electronic structures of the clusters, and the spectral evolution as a function of cluster size was probed systematically. Narrow and well-resolved spectral features were observed at n=13, 19, and 55, consistent with the high symmetry icosahedral structures proposed for these clusters. The measured electron affinities as a function of size in the studied size range do not extrapolate to the bulk work function, indicating that Ti clusters with n=130 may not assume the bulk structure.
