Abstract
We have measured the scatter broadening of pulsars in the direction of the Gum nebula. For the first time. our observations show clear variations of s cattering properties across the Gum nebula. The IRAS-Vela shell is shown to be a high scattering region. Our revised estimations of distances to these pulsars are consistently less bq a factor of 2-3. which has very important consequences for the deduced values of radio luminosity and tr transverse velocity of pulsars.
