Abstract / Bemerkung
We present the measurements of scatter broadening timescales (${{\tau }_{{\rm sc}}}$) for 124 pulsars at 327 MHz using the upgraded Ooty Radio Telescope. These pulsars lie in the dispersion measure range of 37–503 pc cm−3 and declination (δ) range of −57°$\lt \delta \lt 60{}^\circ $. New ${{\tau }_{{\rm sc}}}$ estimates for 58 pulsars are presented, increasing the sample of all such measurements by about 40% at 327 MHz. Using all available ${{\tau }_{{\rm sc}}}$ measurements in the literature, we investigate the dependence of ${{\tau }_{{\rm sc}}}$ on dispersion measure. Our measurements, together with previously reported values for ${{\tau }_{{\rm sc}}}$, affirm that the ionized interstellar medium up to 3 kpc is consistent with the Kolmogorov spectrum, while it deviates significantly beyond this distance.
