  The angular momentum model which couples the spin and charge is discussed as
a possible theory of the quantum Hall effect. The high Landau level filling
fractions 5/2, 7/3 and 8/3 are understood by this model. It is found that 7/3
and 8/3 are the particle-hole conjugates and 5/2 arises due to a limiting level
at 1/2 with Landau level number n=5 which makes the fraction as 5/2.
