Thermal multifragmentation of hot nuclei is interpreted as the nuclear
liquid–fog phase transition inside the spinodal region. The experimental data for

collisions are analyzed. ...It is concluded that the decay process of hot nuclei is characterized by
two size parameters: one density at the transition state and one at the kinetic freeze-out. The similarity between the dynamics of fragmentation and ordinary fission is discussed. The IMF emission time is related to the mean rupture time at the multiscission point, which corresponds to the kinetic freeze-out configuration.

The tensor analyzing power Ayy in inclusive breakup of 9.0 GeV/c deuterons on hydrogen and carbon has been measured at different emission angles of protons. The data are compared to calculations ...within the framework of light-front dynamics by using different deuteron wave functions. The results suggest that the relativistic deuteron structure may depend on more than one independent variable.
