Transport models are the main method to obtain physics information on the nuclear equation of state and in-medium properties of particles from low to relativistic-energy heavy-ion collisions. The Transport Model Evaluation Project (TMEP) has been pursued to test the robustness of transport model predictions to reach consistent conclusions from the same type of physical model. To this end, calculations under controlled conditions of physical input and set-up were performed by the various participating codes. These included both calculations of nuclear matter in a periodic box, which test individual ingredients of a transport code, and calculations of complete collisions of heavy ions. Over the years, five studies were performed within this project. They show, on one hand, that in box calculations the differences between the codes can be well understood and a convergence of the results can be reached. These studies also highlight the systematic differences between the two families of transport codes, known under the names of Boltzmann-Uehling-Uhlenbeck (BUU) and Quantum Molecular Dynamics (QMD) type codes. On the other hand, there still exist substantial differences when these codes are applied to real heavy-ion collisions. The results of transport simulations of heavy-ion collisions will have more significance if codes demonstrate that they can verify benchmark calculations such as the ones studied in these evaluations.

For the purpose of the study of asymmetric and symmetric fission modes of $$^{180,190}$$Hg and $$^{184,192,202}$$Pb nuclei, mass-energy distributions of fission fragments of $$^{180,190}$$Hg and $$^{184}$$Pb formed in the $$^{36}$$Ar + $$^{144,154}$$Sm and $$^{40}$$Ca + $$^{144}$$Sm reactions, respectively, at energies near the Coulomb barrier have been measured using the double-arm time-of-flight spectrometer CORSET and compared with previously measured $$^{192,202}$$Pb isotopes produced in the $$^{48}$$Ca + $$^{144,154}$$Sm reactions. Conclusion is the studied properties of asymmetric fission of $$^{180,190}$$Hg and $$^{184,192,202}$$Pb nuclei point out the existence of well deformed proton shell at Z$$approx$$36 and less deformed proton shell at Z$$approx$$46.

${it In situ}$ identification of the metastable phase during solidification from the undercooled YFeO$$_{3}$$ melt by fast X-ray diffractometry at 250 Hz

A time-resolved X-ray diffraction (XRD) experiment at 250 Hz using a synchrotron radiation source was carried out during the containerless solidification of ReFeO$$_{3}$$ (Re=Y and Lu) in order to identify the metastable phase ${it in situ}$. The metastable phase solidified primarily from the undercooled YFeO$$_{3}$$ melt finally transformed to the stable orthorhombic YFeO$$_{3}$$ phase during the short period of recalescence ($$sim$$0.035 s). Although the metastable phase could not be detected in the as-solidified sample by the powder XRD, the successfully obtained diffraction pattern of the metastable phase in the YFeO$$_{3}$$ system was consistent with that of the metastable hexagonal LuFeO$$_{3}$$ phase.
