Assuming uniformly distributed nucleons in the configuration space at the time of freeze-out, we propose a way for a unique determination of the cell-size in momentum space. Then, using the nucleon occupation probability function in momentum space, we discuss the possibility for the determination of generalized entropy in heavy-ion reaction systems at freeze-out.
