Description

Thermal multifragmentation of hot nuclei is interpreted as the nuclear liquid-fog phase transition inside the spinodal region. The exclusive data for p(8.1 GeV) + Au collisions are analyzed within the framework of statistical model (SSM). It is found that the partition hot nuclei is specified after expansion to a volume equal to Vt = (2.6 ± 0.3)V0. The freeze-out volume is found to be twice as large Vf = (5 ± 1)V0. The similarity between multifragmentation and ordinary fission is discussed

Abstract (Russian)

Термическая мультифрагментация горячих ядер интерпретируется как ядерный фазовый переход жидкость-туман внутри спинодальной области. В рамках статистической модели анализируются эксклюзивные данные для столкновений p(8.1 GeV) + Au. Обнаружено, что разделение горячих ядер определяется после расширения до объема, равного Vt = (2.6 ± 0.3)V0. Обнаружено, что вымороженный объем увеличивается вдвое: Vf = (5 ± 1)V0. Обсуждается сходство между мультрифрагментацией и обычным делением
