Paper Abstract

The narrow low intensity line with maximum at (lambda) -1 equals 15104 cm-1 and width (delta) equals 0.7 cm-1 at T equals 4.2 K have been detected in absorption spectrum of regular LiTmF4 crystal. The observed line belongs to transition form ground state 3H6((Gamma) 2) to lowest level (Gamma) 2 of 3F2 term of Tm3+(4f12) ion. The perturbation, which induces (Gamma) 2 - (Gamma) 2 transition, does not break S4 symmetry of Tm3+ sites. The perturbation of this kind is the interaction of Tm3+ 4f-electrons with electric field, created by quadrupolar moments of lattice ions, which are induced, int urn, by incident electromagnetic wave. To calculate the components of the quadrupolar moment tensors for ions in LiTmF4 single crystal, we have formulated and solved the system of self-consistent linear equations. We take into account interactions between all induced dipolar and quadrupolar moments and their interactions with electric fields of incident wave. The calculated transition probailities per second are in qualitative accordance with experimental data.
