Abstract
We present here our recent results concerning the shape of interstellar plasma spectrum of five pulsars: PSR 0329 + 54, 0437 − 47, 0809 + 74, 0950 + 08 and 1642 − 03 based on complex analysis of multi-frequency observations of diffractive and refractive scintillation of pulsars. We found that in particular directions, the spectrum differs from the Kolmogorov one. Strong angular refraction was detected in the direction to PSR 0329 + 54, 0437 − 47 and 0950 + 08.
