Abstract
THIS communication reports that a programme of observations at Jodrell Bank on ten pulsars has shown that the long term fading of pulse intensities at 408 MHz (ref. 1) has a characteristic frequency width which varies with the dispersion measure6 (∫Ndl) of the source. These results can be explained by a scintillation mechanism due to irregularities of electron density distributed throughout the interstellar medium. The results in this report refer to the total energy density received per pulse, referred to here as pulse energy or intensity.
