摘要：

Observations of a sample of gigahertz-peaked spectrum sources have been carried out using the interplanetary-scintillation method. Scintillations were recorded in six of 53 observed sources; upper estimates for the flux density of the compact emission were obtained for the remaining sources. The contribution of a halo to the integrated flux at low frequencies is considered. Three sources with spectral indices close to −2.5 below the spectral cutoff have been found. The synchrotron self-absorption of emission in the studied sources is discussed.
