Özet

The fusion cross-sections of the 15C + 12C reaction are analyzed using the optical model at energies around the Coulomb barrier. For this objective, the present study consists of two parts. First, three different density distributions of the nucleus 15C are applied to produce the real potential of the double-folding model. Then, the fusion cross-sections are investigated using a one-dimensional potential barrier approximation at astrophysical energies with Morse-type and harmonic-oscillator potentials to make a comprehensive analysis. The theoretical results are in good agreement with the experimental data. We have concluded that the Gaussian-based density distributions are important tools for fusion cross-section calculations with neutron-rich nuclei.
