Abstract (from CDS):

We present the measurements of scatter broadening timescales (τSC) for 124 pulsars at 327 MHz using the upgraded Ooty Radio Telescope. These pulsars lie in the dispersion measure range of 37-503 pc/cm3 and declination (δ) range of -57°< σ < 60°. New τSC estimates for 58 pulsars are presented, increasing the sample of all such measurements by about 40% at 327 MHz. Using all available τSC measurements in the literature, we investigate the dependence of τSC on dispersion measure. Our measurements, together with previously reported values for τSC, affirm that the ionized interstellar medium up to 3 kpc is consistent with the Kolmogorov spectrum, while it deviates significantly beyond this distance.
