The eigenstates of arbitrary-order parasupersymmetric Hamiltonian p corresp
onding to a particle with spin p/2 in the presence of a harmonic oscillator
potential and constant magnetic held directed along the z-axis are constru
cted in terms of eigenstates of a one-dimensional harmonic oscillator. Also
, parasupersymmetric coherent states with degenerate multiplicity of an ad
hoc bosonic annihilation operator of parasupersymmetric eigenstates of the
Hamiltonian mentioned above are calculated.
