摘要：

The transport scattering and single-particle relaxation times which characterize a two-dimensional electron system have been investigated by using thermal neutron irradiation. The ratios of transport scattering time to single-particle relaxation time are observed to vary from 1.7 to 7.8 depending on the electron density. A decrease in single-particle relaxation time is found while the transport scattering time increases as the electron concentrations increase. These phenomena are relevant to the Hall plateau broadening and enhancement of Shubnikov-de Haas oscillations in such an experiment.
