On the absence of mildly recycled radio pulsars amongst the population of ordinary single radio pulsars

Current scenarios for the evolution of binaries predict that only 1%or less of the single radio pulsars in the galactic disk have been recycled in a binary. The fraction of such pulsars amongst the detected single radio pulsars is smaller than this. For magnetic field strengths B > 1012 G the period vs. magnetic field diagram shows no evidence for injection of pulsars at P ∼ 0.5 s. For magnetic field strengths 1010.5 < B < 1011.5 G recycled single pulsars cannot be discriminated from ordinary pulsars, i.e. there is no reason to assume that they are recycled.
