The labyrinth (or two-dimensional wall) structure has been found in single crystals fatigued &axially at zero mean stress. This structure had been observed previously in poIycrystals but it was thought possibte that it rest&d from interactions between n~~~u~ng grains. R&sum&-Nous avons trouvk la st
Luminescence spectra(4.2 K) and etch patterns of thermally deformed anthraccnc single crystals are investigated. It is shown that the Dt band with AE = 235 cm-t (where AE is the energy gap between the bottom of the exciton band and the DI band) is due to the edge dislocations with the emergences at
