Yp. Sukhorukov et al., INFLUENCE OF ELECTRON-IRRADIATION ON THE FUNDAMENTAL ABSORPTION-EDGE OF A COPPER MONOXIDE CUO SINGLE-CRYSTAL, Technical physics letters, 24(2), 1998, pp. 127-129
As a result of irradiation of a CuO single crystal with 5 MeV electron
s, the fundamental absorption edge has an ''Urbach'' appearance and ch
aracteristic features appear near the edge. These changes are explaine
d using a model of polar-center phase nuclei. (C) 1998 American Instit
