| Abstract: | The induction of linear dichroism in (poly) methylmetacrylate films activated with Rhodamine 6G and its base in the spectral range of absorption of these dyes under the action of plane-polarized x-rays with wavelength 0.70Å and intensity 7.5·104 quanta per second has been revealed. The phenomenon is discussed from the standpoint of the radiochemical analog of the photochemical polarization-induced selection of organic molecules with allowance for the structural characteristics of the polymer film components. |
