We study the conditions for the generation and the dynamical evolution of embryonic overcritical vapor bubbles in an overheated asymmetric nuclear matter. We show that the Fermi-surface distortion and memory effects significantly hinder the growth of the bubbles. Moreover, the growth of the bubble is accompanied by characteristic oscillations of its radius R. The characteristic energy E, the damping parameter [Formula Presented] and the instability growth rate parameter [Formula Presented] depend on the relaxation time [Formula Presented] The characteristic oscillations disappear in the short relaxation time limit [Formula Presented] Our approach ignores the fluctuations of the particle numbers in the bubble region and the finite diffuse layer of the bubble. The minimum size of the critical radius [Formula Presented] for which our approach applies is determined by the condition [Formula Presented] where [Formula Presented] is the temperature-dependent surface thickness of the bubble. © 2003 The American Physical Society.
