Abstract. We performed a systematic study of the formation of fragments with different mass ranges in 197Au + 197Au collisions at incident energies between 20–1000 MeV/nucleon and at impact parameter between = 0–0.98. The aim of present study is to understand the complex dependence of fragment production on incident energy and impact parameter. Our results clearly indicate that the QMD simulations of 197Au + 197Au predict different behavior for different mass ranges than for IMF's with a change in incident energy and impact parameter. All charge yields (3 ≤ Zfrag ≤ 12) can be parameterized by a power law (∝ Zfrag) and no signal of liquid-gas phase transition is seen as no unique dependence of σ on impact parameter is seen.
