High-resolution low-temperature absorption spectra in the region of the ^5 I _8 → ^5 I _7, 6, 5, 4, ^5 F _5 transitions in impurity Ho^3+ ions in synthetic forsterite crystals (Mg_2SiO_4) are recorded. Comparison of the observed shape of the spectral lines with the hyperfine structure calculated using crystal-field theory makes it possible to attribute the spectral lines to single centers and dimers for the first time.
