Some Optical Spectra Studies of the Rare Earth Atom Samarium in Inert Gas Matrices at 4.2°K


Foran, Bernard (1962) Some Optical Spectra Studies of the Rare Earth Atom Samarium in Inert Gas Matrices at 4.2°K. Master's thesis, California Institute of Technology. doi:10.7907/0R9G-EA66.


The optical spectrum of samarium atoms trapped in matrices of argon and krypton at 4.2°K was examined. A simple basis for interpretation of the results is presented, in which the matrix perturbation is applied to the free atom in some quantum state of total angular momentum J. The spectra can be correlated with the published data for SmI, but the complexity of the results, particularly in argon, make a detailed interpretation difficult. Some exceptionally sharp triplets with small splittings are considered to be derived from levels of the excited 4f^55d6s^2 configuration, none of which has previously been identified. Fluorescence was observed, corresponding to transitions from an excited state to the ^7F_1 and ^7F_2 levels of the ground state.
