Query: Exact solutions to the Chandrasekhar Page angular equation   Exact solutions are found for the Chandrasekhar Page angular equation which
results when the Dirac equation in a Kerr Newman space time is separated into
its radial and angular parts. The solutions turn out to be remarkably simple in
form while satisfying the asymptotic conditions deduced earlier. The
eigenvalues are found to be the square root of the total angular momentum as
first found by Dirac for flat space; supplemented by a term which is the
product of the mass of the Dirac particle times the specific angular momentum
of the black hole. The additional contribution is what is expected from frame
dragging.
