Neutral ytterbium atoms embedded in solid neon qualitatively retain the structure of free atoms. Despite the atom-solid interaction, the 6s6p ³P(0) level is found to remain metastable with its lifetimes determined to be in the range of ten to hundreds of seconds. The atomic population can be almost completely transferred between the ground level and the metastable level via optical excitation and spontaneous decay. The dynamics of this process is examined and is used to explicitly demonstrate that the transition broadening mechanism is homogeneous.

Forbidden transitions often have moderate energy separations and long lifetimes. They can be induced in elements by external force including laser absorption, magnetic effect, crystal forces and collision with energetic particles. In this paper we discuss the prospects of quantum information processing involving forbidden transitions in the inner shell of Ytterbium. We derive the Schrodinger wave equation for the qubit states with the 3P and 1S as basis states. We also determine a coherent norm calculate the decoherence rate for trapped atoms.

We demonstrate the possibility of measuring the forbidden 1S-2S transition frequency (121 nm) of hydrogen atom by the method of stimulated Raman scattering (SRS) when atom from the 1S level moves to the 2S level through the intermediate 3P level. The frequency of the pumping field (103 nm) is close to the frequency of transition 3P-1S, and the frequency of the stimulated scattering (656 nm) - to the frequency of transition 3P-2S.
