Abstract

It is proposed to search for scintillation of extragalactic sources through the last unknown baryonic structures. Appropriate observation of the scintillation process described here should allow one to detect column density stochastic variations in cool Galactic molecular clouds of order of 3× 10-5 g/cm2 -- that is 1019 molecules/cm2 -- per 10 000 km transverse distance.
