抄録

Far-infrared absorption measurements in the 14-50 cm- 1 range have been performed for oxygen containing silicon crystals in a temperature range of 4.2-35 K. In addition to the previously reported absorption peaks at 29.3, 37.8, 43.3, and 49.0 cm-1 [D. R. Bosomworth, W. Hayes, A. R. L. Spray, and G. D. Watkins, Proc. R. Soc. London A 317, 133 (1970)], a fine structure with peaks at 25.3, 28.3, 30.2, and 33.3 cm-1 has been found, which is considered to be a sideband caused by a coupling between the off-center excitation of the interstitial oxygen and other anharmonic localized excitation of an energy of about 1 cm -1 hc.
