Optical reflection spectra of corundum single crystals grown by HOC and Verneil methods are investigated before and after irradiated by electrons and neutrons using synchrotron radiation polarization (5-30eV).
We use the functional representation of Heisenberg-Weyl group and obtain equation for the spectrum of the model, which is more complicated than Bethes ones, but can be written explicitly through theta functions.
The general formula for R-matrices of slq(2,C) for the highest weight repre- sentations both for general q and for q being a root of unity by generalizing G.Gomez's and G.Sierra's one for semiperiodic representations of slq(2,C) at roots of unity is presented.
