Abstract
A study of Thermally Stimulated Exoelectron Emission (TSEE) obtained f rom alpha-alumina samples after X-ray irradiation at 300 K followed by UV elicitation at 77 K is reported. The observed results, called phot oinduced TSEE (PITSEE) are compared with similar phenomena occurring i n thermoluminescence (PITL) and thermally stimulated conductivity (PIT SC). Under these conditions, two peaks at about 225 and 270 K are rege nerated. The process of regeneration is described in terms of hole tra nsfer and a two-centre Auger mechanism.
