| Abstract: | We report high resolution infrared absorption spectra of LiYF4-Ho exhibiting well resolved nuclear hyperfine structure (hfs). The halfwidths of some hfs components do not exceed 0.03 cm?1. Magnetic field at the nucleus is evaluated. Non-radiative relaxation rates due to phonon emission are estimated. With the help of experimentally found 〈Γ3|Jz|Γ3〉 matrix elements g-factors of the excited crystal field levels are calculated. Some hfs peculiarities are discussed. |
