摘要：
We investigate the geometry of the magnetic field of rotation-powered pulsars. A new method for calculating an angle (beta) between the spin and magnetic dipole axes of a neutron star (NS) in the ejector stage is considered within the frame of the magnetic dipole energy loss mechanism. We estimate the surface magnetic field strength (B-ns) for a population of known neutron stars in the radio pulsar (ejector) stage. The evaluated B-ns(beta) may differ by an order of magnitude from the values without considering the angle beta. It is shown that B-ns(beta) lies in the range 10(8)-10(14) G for a known population of short and middle periodic radio pulsars.
