摘要：
Hole-burning spectra of Eu3+ transitions in axial centers of alkaline-earth fluorides are presented. These spectra, along with optically detected nuclear-magnetic-resonance results, are used to analyze the hyperfine interactions in the 7F0 ground state and in the 5D0 optically excited state. The axial nature of these centers simplified the theoretical analysis from which we obtained the nuclear-quadrupole-interaction strength and the nuclear-magnetic moment quenching factor. An improved value of the ratio of the quadrupole moments of Eu-153 and Eu-151 of 2.553 +/- 0.001 is also given.
