We have shown that for quantum wells placed close to the stress-free surface of the semiconductor heterostructure, the energy relaxation rate of two-dimensional electrons interacting with acoustic phonons at low temperatures (Bloch-GrΓΌneisen regime) is changed considerably in comparison with that of
The Lx/L2 white-line intensity ratio in transition-metal oxides deviates widely from the statistical value of 2 : 1 but shows interesting systematics. In a series of osides of a \_eiven metal, the ratio reaches a maximum for the d' contignation (eg. hln0) and a minimum for the do configuration (e.g.
