Scattering of pulsar radiowave radiation at 102 MHz. The diference from the dependence τp(ν)∞ν-4

Using the 102.5 MHz survey pulse broadening of 17 pulsars was measured. The value of broadening τp is considerably smaller that following from the extrapolation of τp measured at higher frequency. That is the frequency dependence is weaker than τp ∞ ν-4
