INTERSTELLAR SCINTILLATIONS OF PULSARS

Observational data on interstellar difraction and refraction scintilla tions of pulsars are analyzed. The observational data correspond to th e theory of radio wave scintillations on the inhomogeneities with brok en power-law spectrum, which has the turnover point corresponding to a spatial scale a congruent-to 10(13) cm. The spectrum is steep al high spatial frequencies with the three-dimensional power-law index n2 con gruent-to 4,2. The power-law index al low frequencies is n1 congruent- to 3,5.
