Basic Features

After reviewing some basic features of the temperature-governed phase-transitions in macroscopic systems and in atomic nuclei we consider non-thermal phase-transitions of nuclear structure in the example of cluster states. Phenomenological and semimicroscopical algebraic cluster models with identical interactions are applied to binary cluster systems of closed and non-closed shell clusters. Phase-transitions are observed in each case between the rotational (rigid molecule-like) and vibrational (shell-like) cluster states. The phase of this finite quantum system shows a quasi-dynamical symmetry.

A tetramorphic system was discovered in a diketopyrrolopyrrole dye (3,6-bis(4-chlorophenyl)-2-propyl-2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione), with thermosalient effects during thermal phase transitions. Two polymorphs, the red and orange forms, were obtained using liquid-liquid and liquid-gas...
