Abstract
CORRELATION experiment has been performed at INFN-LNS of Catania, using the 4π multi-detector CHIMERA, with the aim of exploring correlations between two and multi light particle produced in 12C+24Mg collisions at 35 AMeV. Particular attention has been paid to the decay mechanisms of Hoyle state, an excited resonant state of 12C produced via the triple-α process and characterized by a pronounced molecular like structure with three α particles. The study of the Hoyle state is essential for nucleosynthesis, but it also represents a clearly isolated state that can be studied as a three-α cluster system.
Highlights
Heavy Ion collisions at intermediate energies represent an important tool to produce and to study systems in extreme conditions of temperature, density and excitation energies, they are the only terrestrial means to access the equation of state of asymmetric nuclear matter
11th International Conference on Clustering Aspects of Nuclear Structure and Dynamics correlations between particles emitted during these reactions play a crucial role to understand involved dynamics and to investigate some of the spectroscopic properties of several species produced during the evolution of systems
Multi particle correlations have been used to explore the competition between sequential and direct decay mechanisms of resonances produces in these reactions; in particular here three α correlation has been analyzed to study the decay processes of Hoyle state, the second 0+ excited state of 12C at an energy of 7.65 MeV
