because of the properties showed by the two kinds of processes. Effectively, a long-term memory process, like an Arfima process, is a stochastic one, while a chaotic process is by definition a deterministic one. However, this question finds its origins in recent works of Peters (1991, 1994) setting

The occurrence of these levels could

Thermoluminescence Spectroscopy of Defects, experimental methods such as measurements of space-charge-limited currents and thermally stimulated conductivity, is more simple and does not introduce additional defects in investigated specimens. However, to determine the sign of charge carriers contributing to the glow, one needs additional data.
