Paraelectric resonance of annealed KCl:KOH crystals

Paraelectric resonance is used to study the tunneling behavior of OH- in both as-grown and annealed KCl crystals. The differences observed between the two types of crystals indicate that internal stresses broaden the resonance lines, and in as-grown crystals internal stresses displace the energy levels within the lowest manifold of tunneling states. © 1969.
