We clarify the relationship between spin–orbit (SO) splitting and three-nucleon forces (3NFs) derived from chiral effective field theory. While the influence of 3NFs on enhancing SO splitting is well known, the mechanisms underlying this enhancement have remained elusive. Through the irreducible tensor decomposition of the chiral 3NF, our investigation reveals that the rank-1 tensor component...

The synthesis of carbon and oxygen plays a central role in nuclear astrophysics, as the reactions 3α → ¹²C + γ and ¹²C(α,γ)¹⁶O govern the stellar C/O ratio and influence stellar evolution and nucleosynthesis. Despite their importance, a consistent theoretical description of these processes at low energies remains challenging due to strong Coulomb effects. In this talk, I present a...

It has been well known that nuclear collective excitations significantly affect heavy-ion reactions at energies around the Coulomb barrier. A prominent example is the large enhancement of fusion cross sections at subbarrier energies. To account for such enhancement, the coupled-channels approach has been widely employed.
While the coupled-channels approach has been successful in...

The ¹²C+¹²C fusion reaction plays essential roles in various astrophysical phenomena, including carbon burning in massive stars, Type Ia supernova ignition, and X-ray superbursts. However, its reaction rate at low temperatures remains highly uncertain due to difficulties in direct measurements. In this talk, we discuss our recent microscopic studies of the ¹²C+¹²C fusion reaction based on...
