摘要
To prove directly the relation between the emergence of narrow lines in the dislocation photo-luminescence spectrum of germanium after the second deformation stage and the splitting value-DELTA of perfect dislocations a special orientation of crystals at the second deformation stage is used. The samples contain dislocations either with DELTA > DELTA-0 or with DELTA < DELTA-0 (DELTA-0 is the equilibrium splitting value). The narrow lines are found to arise only on the short-wave side of the line corresponding to equilibrium splitting at DELTA > DELTA-0 and on the long-wave side at DELTA < DELTA-0. This result and the unique regularity of the narrow line arrangement observed experimentally are considered as a convincing evidence for the effect of the distance between partials on the radiation energy associated with the 90-degrees partials only.
