Abstract:
A complete sample of core-dominated radio sources has been studied
using the interplanetary-scintillation method. In total, 72 sources
were observed, with scintillations detected in 28 of them. The
remaining sources have upper limits on their flux densities.
Integrated flux densities are estimated for 24 sources. Cut-offs have
been observed in the spectra of many sources. The thermal-electron
densities have been estimated, assuming that these cut-offs are due to
free-free absorption of the synchrotron radio emission.
