Abstract
A deformed boson mapping of the Marumori type is derived for an underl ying su(2) algebra As an example, we bosonize a pairing Hamiltonian in a two level space, for which an exact treatment is possible. Comparis ons are then made between the exact result, our q-deformed boson expan sion and the usual non-deformed expansion.
