    Notes: [Auszug] The fluctuation power spectrum of a sequence of momentary pulse energies formed using an integration gate narrower than the pulse width displays features not visible with a wider gate. The analysis indicates that the class two period is a function of phase within the pulse profile. The statistical ...

    Notes: [Auszug] The phenomena have been observed using linearly polarized feeds at 318 MHz and 606 MHz and a circularly polarized feed at 430 MHz. Further inspection of dual frequency recordings (318 MHz/111-5 MHz) from 0834 + 06, 1133+16 and 1237 + 25 shows that both types of nulls are correlated over hundreds of ...

    Description: Both average and individual pulse polarization measurements at 430 MHz are presented for three pulsars: PSR 0823 + 26, PSR 0834 + 06, and PSR 2303 + 30. In each case, the average Stokes parameter waveformes are found to depend on the individual pulse polarization properties in a complicated manner. The average waveforms are in general depolarized by pulse-to-pulse fluctuations in polarization state at a given longitude. Two of the three objects exhibit variations of both linear and circular polarization which are associated with quasi-periodic subpulse modulation phenomena in a manner similar to that reported for linear polarization in PSR 0809 + 74 by Taylor et al. (1971.).

    Description: An investigation of the intensity fluctuations of 28 pulsars near 0.4 GHz indicates that scintillation spectra have a Gaussian shape, scintillation indices are near unity, and the scintillation bandwidth depends linearly on dispersion measure. Observations near 2.5 GHz suggest a strong dependence of the frequency at which scintillation indices fall below unity on dispersion measure. Multistation measurements of scintillation provide values or limits for the scale size of the scattering diffraction pattern. The dependences of scattering parameters on dispersion measure is discussed in terms of the current models. It is suggested that any line of sight through the galaxy encounters increasingly rare, increasingly large deviations of thermal electron density on the scale of 10 to the 11th power cm.

    Description: The frequency dependence of the parameters of interstellar scattering between 837 and 8085 MHz for the Vela pulsar are consistent with thin-screen models of strong scattering. The magnitudes of the parameters indicate an anomalous turbulence along the path when they are compared with results for other pulsars with comparable column densities of free electrons in the line of sight. This anomaly is due presumably to the Gum Nebula. The decorrelation frequency, appropriately defined, is related to the pulse broadening time by 2 pi as predicted theoretically.

    Description: Time-averaged flux-density spectra of ten pulsars have been obtained on the basis of simultaneous observations at six frequencies between 250 and 8085 MHz. The effects of interstellar scintillation on the accuracy of the measurements are discussed. All of the pulsars exhibited a power-law spectrum at high frequencies with spectral indices between negative 1.6 and negative 3.0. Several of the pulsars show a more positive spectral index at the low-frequency end of the data.
