We have employed spectral-hole-burning, coherent-transient, and optical-rf double-resonance techniques to measure various parameters associated with the 580.8-nm /sup 7/F/sub 0/-/sup 5/D/sub 0/ transition of Eu/sup 3+/ doped into Y/sub 2/O/sub 3/. In particular, we have measured the hyperfine splittings of the terminal levels (for both /sup 151/Eu and /sup 153/Eu), an effective thermalization rate of the ground-state (/sup 7/F/sub 0/) hyperfine manifold over the temperature range of approx. =4--15 K, and the homogeneous linewidth of the optical transition over the range of approx. =14--35 K. Large ratios of inhomogeneous to homogeneous linewidth at elevated temperatures (10/sup 3/ at 25 K) and long ground-state hyperfine thermalization times (>30 h at 4 K) make this an interesting crystal in the context of spectrally addressable optical memories.
