Barrier distributions of the ²⁴Mg + ^{90, 92}Zr systems: Influence of energy dissipation

NUCLEAR REACTIONS ^90,92Zr(²⁴Mg, ²⁴Mg), (²⁴Mg, ²⁴Mg'), E=68-88 MeV; measured scattered ²⁴Mg ions using the multidetector CHIMERA system, and backscattered ions by rings of Si detectors placed at different angles, σ(E, θ) at the Tandem MP accelerator of the LNS-INFN-Catania; deduced Coulomb barrier distributions as function of incident beam energy and angle, influence of energy dissipation. Comparison with predictions of the standard coupled channels calculations, and with coupled channels plus random matrix theory (CC+RMT).

Experimental investigation of α condensation in light nuclei

NUCLEAR REACTIONS ¹²C(¹⁶O, ²⁸Si)⁴He/⁶Li/⁷Li/⁷Be/⁹Be/¹⁰B/¹¹B/¹¹C/¹²C/¹³C/¹¹N/¹²C/¹⁵O/¹⁵N/¹⁶O/F/Ne/²⁰Ne/²⁴Mg/²⁸Si, E=160, 280, 400 MeV from the K800 cyclotron at the LNS-Catania accelerator facility; measured reaction product yields, σ, Eα, Iα using the Charged Heavy Ion Mass and Energy Resolving Array (CHIMERA) and Femtoscope Array for Correlation and Spectroscopy (FARCOS); deduced raw α-particle multiplicity, particle-identification plots (PIDs), interaction time plot, distribution of α-particle energies, excitation functions, Q values for different reaction channels, branching ratios for the 7-α breakup modes. Experiments aimed at search for α-gas states in ¹²C, ¹⁶O, ²⁰Ne, ²⁴Mg, ²⁸Si. Results described by a hybrid of sequential decays and multiparticle breakup mechanisms, as no signatures for α condensation observed. Comparison of measured yields to the extended Hauser-Feshbach (EHF), and comparison of 7-α particle states to Fermi breakup model predictions.
