  Operators, refered to as k-fermion operators, that interpolate between boson
and fermion operators are introduced through the consideration of two
noncommuting quon algebras. The deformation parameters for these quon algebras
are roots of unity connected to an integer k. The case k=2 corresponds to
fermions and the limiting case k going to infinity to bosons. Generalized
coherent states and supercoherent states are investigated. The Dirac quantum
phase operator and the Fairlie-Fletcher-Zachos algebra are also considered.
