英文摘要Multiplicity fluctuation of the target evaporated fragments emitted in 290 MeV/u C-12-AgBr, 400 MeV/u C-12-AgBr, 400 MeV/u Ne-20-AgBr and 500 MeV/u Fe-56-AgBr interactions is investigated using the scaled factorial moment method in two-dimensional normal phase space and cumulative variable space, respectively. It is found that in normal phase space the scaled factorial moment (ln < F-q >) increases linearly with the increase of the divided number of phase space (lnM) for lower q-value and increases linearly with the increase of lnM, and then becomes saturated or decreased for a higher q-value. In cumulative variable space ln < F-q > decreases linearly with increase of lnM. This indicates that no evidence of non-statistical multiplicity fluctuation is observed in our data sets. So, any fluctuation indicated in the results of normal variable space analysis is totally caused by the non-uniformity of the single-particle density distribution.
