ESR Investigation of the Dynamical Behavior of Hydrogen Atoms in CaF2

摘要

The techniques of ESR are employed to investigate the motion of H atoms in the lattice of CaF2. It is found that the atoms are quite stable against motion at temperatures below 100deg;C but migrate readily through the lattice at temperatures 114deg;C. The character of the initial decrease in intensity of the spectrum seems to be ``bimolecular.'' Later stages are exponential, and are governed by an activation energy of 1.2 eV.
