[en] As a part of statistical freeze-out study in antisymmetrized molecular dynamics (AMD), an analysis of "1"1"2Sn + "1"1"2Sn at 50 MeV/nucleon is presented. Using the self-consistent method combined with the Modified Fisher model, the fragmenting source density, ρ/ρ0 = 0.69 ± 0.03, temperature, T = (6.1 ± 0.2) MeV, are extracted. By comparing the maximum density in the system during the time evolution of AMD calculation, a significantly lower density is found for the fragmenting source density. The extracted fragmenting source density and temperature are very similar to those for "4"0Ca + "4"0Ca at 35 MeV/nucleon and "6"4Zn + "1"1"2Sn at 40 MeV/nucleon. These indicate that there is a common statistical freeze-out volume at the time of the formation of intermediate mass fragments (IMFs) in AMD transport model. (authors)
