Energy Spectra and Pulse Shapes of Pulsars at Metre Wavelengths

Flux densities, pulse energy densities and mean pulse shapes of pulsars have been measured at frequencies of 61 and 102 5 MHz. In general, with increasing wavelength, the mean pulse width becomes larger and its profile becomes less complex. Instantaneous spectra obtained by simultaneous measurements...

Description
Summary:Flux densities, pulse energy densities and mean pulse shapes of pulsars have been measured at frequencies of 61 and 102 5 MHz. In general, with increasing wavelength, the mean pulse width becomes larger and its profile becomes less complex. Instantaneous spectra obtained by simultaneous measurements show marked variability, but the mean spectrum is a stable characteristic of each pulsar. A common feature of pulsar mean spectra is a low frequency cutoff below about 100 MHz. The nature of this cutoff is discussed.
