Strongly resonating bosons in hot nuclei Academic Article uri icon


  • 2019 American Physical Society. When two heavy ions near the Fermi energy collide, a warm and low-density region can form in which fragments appear. This region is mainly dominated by proton (p) and alpha () particles. In such an environment, the particles interact with each other and, especially through strong resonances, form complex systems such as Be8 and C12. Our experiments show that Zn70(64)(Ni64)+Zn70(64)(Ni64) reactions at E/A=35 MeV/nucleon levels of Be8 appear around relative energies Eij=0.092 MeV, 3.03 MeV as well as above 10 and 100 MeV. We propose a different method to derive the correlation function based on the relative transverse energy distribution to minimize the experimental uncertainties. For the 3 systems, multiresonance processes give rise to excited levels of C12. In particular, the Hoyle state at 7.654 MeV excitation energy shows a decay component through the ground state of Be8 and also components where two different couples are at relative energies consistent with the ground state of Be8 at the same time.
