Squeezing mode in nuclear collisions — •K.

The time dependent Schroedinger equation
is solved analytically for a simplified model of moving infinite walls.
A new knock-out mode is described which might occur during heavy ion
collisions. The outer shell-nucleons are ionized due to the increase of
level energy when two nuclei are
approaching fast enough. This is
analogous to the Mott effect but in contrast occurs only if the
reaction time is short enough that no common ionization threshold
in the compound system is established. To demonstrate this pure
nonequilibrium effect a simulation of realistic heavy ion collision by
a nonlocal Boltzmann equation is performed.
