Abstract
Two parameters such as magnetic fields near the light cylinder \(B_{lc} \) and rates of rotational energy losses \(\frac{dE}{dt} \) for 1795 radio pulsars without high energy emission (R), 52 radio loud gamma-ray pulsars (\(\gamma\)+R), 33 radio quiet gamma-ray pulsars (\(\gamma\)) and 61 radio loud X-ray pulsars (X+R) are compared with each other in this work. Pulsars with registered X-ray and gamma-ray emission have the higher median values of \(B_{lc} \) and \(\frac{dE}{dt} \) as compared to the population of ordinary radio pulsars. There is a trend of increasing of luminosities in X-ray and gamma-ray ranges for higher values of magnetic field near the light cylinder. We hypothesize that non-thermal X-ray and gamma-ray emissions are generated near the light cylinder by the synchrotron mechanism.
