  Using the Wigner distribution function, we analyze the behavior on phase
space of generalized coherent states associated with the Morse potential
(Morse-like coherent states). Within the f-deformed oscillator formalism, such
states are constructed by means of the two following definitions: {\it i)} as
deformed displacement operator coherent states (DOCSs) and {\it ii)} as
deformed photon-added coherent states (DPACSs).
