Scientific paper

Possible observational consequences of the adiabatic and nonadiabatic evaporation of primordial mini black holes (masses of 10 to the 14th to 10 to the 15th g) are considered. It is shown that pair-produced ultrarelativistic electrons and positrons would transfer their energy to the background radiation field as a result of inverse Compton losses to the background radiation and that such energy transfer could distort the presently observed background spectrum in the optical, X-ray, and gamma-ray regions if the mean density of primordial mini black holes was in excess of 10 to the -37th g/cu cm. It is concluded that the initial deviations of the universe from homogeneity and isotropy were not large at the time these primordial mini black holes were formed.
