title: Persistent spectral hole burning due to deuteron tunneling in SrF(2):Pr(3+):D(-).
abstract: We report the observation of persistent spectral hole burning due to a mechanism that is new to inorganic materials, i.e., light-induced deuteron (or proton) tunneling. Measurements were made on (3)H(4) ? (1)D(2) transitions of SrF(2):Pr(3+) centers having two D(-) ions as near neighbors. The spectral holes exhibit hyperfine structure dominated by very large (~100-MHz) pseudoquadrupole splittings in the singlet ground state.
