According to the method for analyzing physical and/or chemical properties
of the surface layer of a solid as per claim 1, the surface layer is
activated by a unit irradiation pulse and, when the irradiation is over,
is deactivated by keeping the solid at a constant temperature and
subsequently heating it, the spectrum of the energy quanta emitted by the
surface layer of the solid is recorded during the deactivation; the
spectrum of the emitted energy quanta recorded at a constant temperature
provides data on the loosely coupled states of the surface layer and
their half-lives and the thermoluminescence spectrum recorded during the
heating gives information on phase and relaxation transition temperatures
in the surface layer.
