The kink migration energy is evaluated by modifying the line tension model of dislocation. A sinusoidal variation of Pierels potential is used for dislocation, which gives a neglible migration energy for kink motions for typical metals. This confirms the general expectation that kinks can move freely along dislocation lines with no necessity of activation.

A double oscillatory potential which is found to be useful in modeling the problem of atomic rate transition is analysed by effective hamiltonian method. The result is the same as rigorous analysis. A back tunneling of the particle due to the accumulation effect on final local state must be taken into account in this double oscillatory case, suggesting that the golden rule of transition is a rough approximation and is not applicable to bound state tunneling.

Single crystal of TGS are preapred by acqeous solution-cooling method.Powder of TGS is obtained by stoichiometric mixing of sulfuric acid and glycine solution.A systematic analysis of the crystal geometry let us be able to find out the polar axis of the grown TGS crystal easily and to cleave the crystal along its b face accordingly. The resultingly crystal plates are being used for pyroelectric thermal detector.
