| Abstract: | The optical constants of single crystals of hexagonal selenium in the region of the intrinsic absorption edge in polarized light were investigated. The absorption edge for light polarized normal to the optical axis of the crystal is displaced towards longer wavelengths. The absorption maximum of hexagonal selenium for a wavelength of 0·6  is interpreted as the maximum corresponding to interaction between neighbouring chains and in connection with this the position of the absorption edge of different modifications of selenium is discussed.
In conclusion the author wishes to thank Dr. E. Klier and R. Ku  el for valuable discussions and advice. He thanks laboratory assistants J. Ontl and O. Kundrátová for help in the work. |
