    "abstract": "A novel mechanism of prompt nuclear fragmentation is proposed. Assuming\nmicro-canonical or canonical equilibrium, it is shown that a strong enhancement\nof the accessible phase space volume, due to the diffuceness of the nuclear\nsurface, leads to dynamical instabilities of hot nuclei and to prompt\nfragmentation. Equations are derived for the transition temperature T_T, for\nwhich the thermodynamical surface tension vanishes, as well as for the\nthermodynamical fissility parameter chi_td.",
