Scientific paper

The possibility of gravitational scintillation which would lead to an estimate of the missing mass is examined analytically using the 'thin phase screen' approximation. The statistical properties of the thin phase screens which would represent the global effect of the assumed mass distribution on the propagation of electromagnetic waves along the whole line of sight are derived. It is concluded that there is no detectable radio source small enough to produce observable effects; however, constraints on the mass distribution are derived from the observed angular size of quasars.
