Scientific paper

The flux densities of 14 pulsars are observed for over 1 year at an observing frequency of 610 MHz, using an NRAO 26 m telescope. The observed time scales for long-term flux variation for seven pulsars are in good agreement with refractive scintillation theory. Four pulsars, including the Vela pulsar, have observed time scales that are in poor agreement with theoretical predictions. Pulsars predicted to have extremely long refractive scintillation time scales are observed to have stable fluxes. These pulsars therefore have intrinsically stable luminosities. No scintillation modulation depth greater than 0.4 is noted in the large sample. The results are best described by a Kolmogorov spectrum of electron density inhomogeneities.
