We study Dirac equation in Kerr-Taub-NUT spacetime. We use Boyer-Lindquist
coordinates and separate the resulting equations into radial and angular parts.
We get some exact analytical solutions of the angular equations for some
special cases. We also obtain the radial wave equations with an effective
potential. Finally we discuss the potentials by plotting them as a function of
radial distance in a physically acceptable region.Comment: 29 pages, 4 figures, extended discussion part, one reference added,
