Orientation-dependent time-integrated intensity

By exploiting the orientation dependence of the nuclear resonant scattering signal, the diffusion mechanism can be elucidated at the atomic level. The orientation-dependent time-integrated intensity (ODIN) is given by... 

Region III, IV the late stage of SD, i.e., the process where the oriented domains grow with self-similarity. The reason for the time dependences of the integrated intensity is unclear. 

Diffracted intensities, proportional to pole densities, may be put on a times-random basis by comparing them with intensities diffracted by a random specimen [9.20]. The random specimen should be of the same material as the textured specimen and, for a transmission method, it should have the same value of fit if not, a correction has to be made that will depend on the transmission method involved. The random specimen itself is usually made by compressing and sintering a powder [9.11, 9.12]. The randomness of grain orientation in this specimen must be checked by determining its diffraction pattern with a diffractometer in the usual way the measured integrated intensities of all lines should agree with those calculated by Eq. (4-21).
