| Abstract: | Photon echo decays of several impurity paramagnetic ions are calculated,the historical average of each lattice nuclear spin flip is described by a bivalued random telegraph process,and the spatial average is obtained according to the crystal structure. The results are very close to those of Monte Carlo simulations. From the experimental observations,we obtained that all samples have a universal decay form. |
