The braking index predicted in our model is, in general, less than n = 3 (the value for pure magnetic dipole radiation), in agreement with the reported values of n < 3 for five young radio pulsars. With an accuracy of 30% or better, our model reproduces the age, braking index, and third-frequency derivative of the Crab pulsar for a disk mass inflow rate in the range of 3 x 10(16)-10(17) g s(-1).en-USJournal Article2019-09-2010.1086/320927
