where rp is the radius of the star. Eq. 4.13.16 gives about 3x 10 particles/sec at Q = Qo in the case of pulsar in Crab.
Let us estimate the energy spectrum of accelerated particles emitted from the rotated magnetic star for the all time with taking into account the braking of the star's rotation. If the rate of injection is constant at the phase po, the mean energy of accelerated particles (e) will be about 80% from Emax (Goldreich, 1969). In this case the differential energetic spectrum of accelerated particles ejected into interstellar space will be
