Role of the Hoyle state in the 12C+12C fusion at low energies

Role of the Hoyle state in the 12C+12C fusion at low energies

The 12C+12C fusion reaction is investigated in a multichannel folding model, using the density-dependent DDM3Y nucleon-nucleon interaction. The 12C(01+, 2+, 02+, 3−) states are included, and their densities are taken from a microscopic cluster calculation. Absorption to fusion channels is simulated...
