Microscopic description of C+C fusion reactions at nuclear astrophysical energies
K. Nagao, K. Hagino, K. Uzawa
The C + C fusion reaction plays a key role in several astrophysical phenomena. However, it is difficult to determine its cross sections in the relevant energy region…
Spin-Dependent Nucleon-Nucleus Interactions Constrained by Neutron Observables and Their Impact on Near-Barrier Proton Fusion
Kyoungsu Heo, Myung-Ki Cheoun, Kouichi Hagino
We investigate the role of spin-dependent nucleon-nucleus interactions in nuclear reactions. To this end, we use neutron spin observables to constrain the dominant central spin-spi…
Re-examination of fusion hindrance in astrophysical C+C and C+C reactions
Kotaro Uzawa, Kouichi Hagino
To determine the energy dependence of fusion cross sections at extremely low energies is crucial for various astrophysical processes. In the previous study by Jiang et al. [Phys. R…
A simple schematic model for a cross section deficit in C+C fusion reactions
K. Hagino
A cross section deficit phenomenon has been observed in C+C fusion reactions at astrophysical energies, at which fusion cross sections are suppressed in the off-reson…
