Production mechanism of hot nuclei in violent collisions in the Fermi energy domain

A production mechanism of highly excited nuclei formed in violent collisions in the Fermi energy domain is investigated. Collision of two nuclei is decomposed into several stages which are treated separately. A simple phenomenological approach based on the exciton concept is used for the description of pre-equilibrium emission. For violent collisions, a modified spectatorparticipant scenario is...

Production of Hot Nuclei in Fermi Energy Domain: from Peripheral to Central Collisions

The production mechanism of highly excited nuclei in the Fermi energy domain is investigated. A phenomenological approach, based on the exciton model, is used for the description of pre-equilibrium emission. A model of deep inelastic transfer is employed for the peripheral collisions in the post-pre-equilibrium stage. An approach to describe more central collisions is proposed. A geometric over...

Production mechanism of hot nuclei in Fermi energy domain: from peripheral to central collisions

A detailed knowledge of the production mechanism of hot nuclei is desirable for the understanding of multifragmentation. In this article, a framework based on simple phenomenological assumptions is presented. A more detailed description can be found in [1]. Pre-equilibrium emission is a process where fast particles are emitted during the initial approach of the projectile and target. In the pre...
