Scientific paper

Results are presented for measurements of the polarization properties of individual pulses from the pulsars PSR 0834, 0950, and 1113 at a frequency of 86 MHz (wavelength of 3.5 m). The degree of linear polarization at this frequency is found to be 40% for PSR 0834, 70% for PSR 0950, and 50% for PSR 1113. It is shown that Faraday depolarization is negligible for PSR 0950 and 1113, but may amount to 30% to 40% of the actual linear polarization for PSR 0834. Two distinct flux components with a mean difference of approximately 20% in degree of linear polarization are detected for PSR 1113. Comparison with previous measurements at 60 and 2295 MHz as well as in the range from 410 to 1400 MHz indicates that the degree of linear polarization is greater at 86 MHz than at shorter wavelengths.
