| dc.description | Optical-RF double-resonance techniques have been used to study the superhyperfine transition frequencies in a series of Pr<sup>3+</sup> centres in CaF<sub>2</sub>:Pr<sup>3+</sup> and SrF<sub>2</sub>:Pr<sup>3+</sup> crystals. In these centres Pr<sup>3+</sup> substitutes for Ca<sup>2+ </sup>(Sr<sup>2+</sup>) and the excess positive charge is compensated by F<sup>-</sup>, H<sup>-</sup>, D<sup>-</sup> or T<sup>-</sup> interstitial ions along (100) directions yielding centres of C<sub>4v</sub> symmetry. The superhyperfine structure is associated with RF-induced nuclear spin flips of the lattice <sup>19</sup>F<sup>-</sup> ions and of the interstitial ions that are coupled to the Pr<sup>3+</sup> ion. Some qualitative conclusions are drawn about the position of the Pr<sup>3+</sup> ion, the nearest-neighbour F<sup>-</sup> ions and the interstitial ions in the lattice. |
