Scientific paper

The 25-m Dwingeloo radiotelescope was used to search for radio bursts of approximately 3 GHz. It is thought that black holes of mass smaller than 10 to the 15th grams would ultimately annihilate into a burst of energetic photons and particles which might produce a radio pulse with a characteristic frequency of approximately 3 GHz and an energy of approximately 10 to the 32nd erg. No events attributable to black holes were observed. The limiting sensitivity is calculated and is found to be comparable to limits derived from other analyses of radio data. It is suggested that primordial black holes of less than 10 to the 15th grams could never have exceeded 10 to the minus 10th of the total mass of globular cluster.
