The potential model for nuclear astrophysical reactions requires a considerably shallow nuclear potential when a square-well potential is employed to fit experimental data. We discuss the origin of this apparently different behavior from that obtained with a smooth Woods-Saxon potential, for which a deep potential is often employed. We argue that due to the sharp change of the potential at the boundary the radius parameter tends to be large in the square-well model, which results in a large… Expand

Heavy-ion fusion reactions at extreme sub-barrier energies
The study of fusion reactions at extreme sub-barrier energies has seen an increased interest in recent years, although difficult to measure due to their very small cross sections. Such reactions areExpand
Resonance width for a particle–core coupling model with a square-well potential
We derive a simple formula for the width of a multi-channel resonance state. To this end, we use a deformed square-well potential and solve the coupled-channels equations. We obtain the $S$-matrix inExpand

Nuclear reactions in astrophysics.
At all times and at all astrophysical scales, nuclear reactions have played and continue to play a key role. This concerns the energetics as well as the production of nuclides (nucleosynthesis).Expand

Gamma-ray yields from 12C + 13C reactions near and below the coulomb barrier
Abstract The γ-ray yields from low-lying transitions in heavy residual nuclei produced in the 12 C+ 13 C reaction have been measured from E c.m. = 3.1 to 11.9 MeV using a Ge(Li) detector. Total crossExpand
Upper Limit on the molecular resonance strengths in the 12 C+ 12 C fusion reaction
Molecular resonances complicate the prediction of the carbon fusion rate at the energies of astrophysical relevance. By comparing the cross sections of three carbon isotope fusion reactions, 12C+12C,Expand
Sub-barrier fusion of the oxygen isotopes: A more complete picture.
It is found that a multidimensional model is necessary to describe the enhanced fusion cross sections in oxygen and the two-dimensional incoming wave boundary condition model suggests that a complete description of the fusion, inelastic, and elastic cross sections is possible. Expand
