Scientific paper

The author calculates the polarization position angle as a function of pulse longitude and polarization limiting radius in radio pulsars assuming a vacuum magnetic field. He also estimates the polarization radius rpl, based on the calculations of Cheng and Ruderman and Stinebring. It is found that for rotation periods P < 0.06 s this radius is rpl ≈ 2×105(P/1 s)-2cm and for P > 0.06 s it is rpl ≈ 9×108(P/1 s)0.4cm for a surface magnetic field strength of 1012G and radio frequency of 109Hz. For short rotation periods, rpl approaches the light cylinder radius rlc.
