Abstract : The creation of anisotropic defects as H- and Vk-centers in alkalihalides leads to an anisotropic distortion of the crystal. Rotation of these defects from one orientation to another by irradiation with polarized light leads to a change of the macroscopic dimensions of the crystal. Together with optical absorption measurements the double force tensor describing the mechanical interaction of the defect with the lattice is obtained.
