radio emission – Giant Pulses (GPs) and Abnormally Intensive Pulses (AIPs). Both of
them are quite rare phenomena – so far they are known only for a handful of pulsars.
GPs were being detected in the range from 23 MHz to 15 GHz
and consist of the
 at decimeter wavelengths, and, similar to GPs, they are narrower and much more
brighter than the average proﬁle of radio emission.
Our eﬀorts were concentrated to determine the energy distribution of single pulses.
It is known that GP energies are distributed by the power law, with the exponent
depending on the pulsar, observed frequency and range of pulses widths . The
exponent typically varies from −0
.9 to −3.2 for the cumulative distribution.
work, the energy distribution of GPs from the Crab pulsar at 600 and 1650 MHz were
was obtained using the data of B0809+74 at 23 MHz. We compared the distributions
of GPs and AIPs to the appropriate distribution of regular pulses. Other statistical
properties of both GPs and AIPs are also discussed. The results can be used to set the
constrains on the theories of pulsar radio emission.
