Abstract:
Data on the profiles and polarization of the 10- and 20-cm emission of
radio pulsars are used to calculate the angle β between the
rotational axis of the neutron star and its magnetic moment. It is
shown that, for these calculations, it is sufficient to use catalog
values of the pulse width at the 10% level W10, since the broadening
of the observed pulses due to the transition to the full width W0 and
narrowing of the pulses associated with the emission of radiation
along tangents to the field lines approximately cancel each other out.
The angles β1 are calculated for 283 pulsars at 20cm and 132
pulsars at 10cm, assuming that the line of sight passes through the
center of the emission cone.
