Abstract
This thesis intends to show that the strong correlation observed between the braking
indices (n) and the slowing down age ( ) of pulsars with alignment and counter
alignment. We will calculate the braking index of young pulsar which is crab pulsar
is less than 3 by using the braking mechanisms, electromagnetic and gravitational
radiations,& the braking index for quadrupole radiation is equal to 5, and to show
the ratio between the gravitational and electromagnetic contributions to the pulsar
spin down rate its present values are always less than one
