| dc.description | The diffraction contrast method for studying dislocations in quasi-crystals is discussed and summarized. As a general principle, by finding five linearly independent extinction reflections g<sub>i</sub> (i=1, 2, 3, 4, 5), under which the dislocation contrast is invisible, the direction of the Burgers vector b of a dislocation in an icosahedral quasi-crystal is determined to be the vector product of these five reciprocal vectors. By applying this method we determined the Burgers vector b of a dislocation in an Al<sub>70</sub>Pd<sub>20</sub>Mn<sub>10</sub> icosahedral quasi-crystal to be parallel to the six-dimensional vector (2-10-20-1) which possesses a rather large phason component. |
