Elastic and Raman scattering of 9.0 and 11.4 MeV photons from Au, Dy and In

Monoenergetic photons between 8.8 and 11.4 MeV were scattered elastically and in elastically (Raman) from natural targets of Au, Dy and In.15 new cross sections were measured. Evidence is presented for a slight deformation in the 197Au nucleus, generally believed to be spherical. It is predicted, on the basis of these measurements, that the Giant Dipole Resonance of Dy is very similar to that of 160Gd. A narrow isolated resonance at 9.0 MeV is observed in In.Comment: 31 pages, 11 figure

EXCITON ATTENUATION IN THE POLARITON LUMINESCENCE SPECTRA OF CRYSTALS OF THE TYPE CdTe

The analysis of low-temperature photoluminescence (LTPL) spectra of crystals is widely used to improve the methods of non-destructive testing and diagnostics of crystalline and polycrystalline semiconductor structures based on them. In this case, it is of particular importance to study the spectra of exciton luminescence (EL) as the most sensitive and direct optical method, which makes it possible to obtain the finest and most reliable information on defects in a semiconductor material
