Fusion cross-sections for inertial fusion energy
The application of selective resonant tunneling model is extended from d 1 t fusion to other light nucleus fusion reactions, such as d 1 d fusion and d 1 3He. In contrast to traditional formulas, the new formula for the cross-section needs only a few parameters to fit the experimental data in the energy range of interest. The features of the astrophysical S-function are derived in terms of this...
متن کاملFusion cross sections at deep subbarrier energies
A recent publication reports that heavy-ion fusion cross sections at extreme subbarrier energies show a continuous change of their logarithmic slope with decreasing energy, resulting in a much steeper excitation function compared with theoretical predictions. We show that the energy dependence of this slope is partly due to the asymmetric shape of the Coulomb barrier, that is its deviation from...
متن کاملSolar fusion cross sections II: the pp chain and CNO cycles
We summarize and critically evaluate the available data on nuclear fusion cross sections important to energy generation in the Sun and other hydrogen-burning stars and to solar neutrino production. Recommended values and uncertainties are provided for key cross sections, and a recommended spectrum is given for 8 B solar neutrinos. We also discuss opportunities for further increasing the precisi...
متن کاملSolar Abundance of Elements from Neutron-capture Cross Sections
Introduction: Light elements, H and He, covering the solar surface are widely believed to be dominant inside the Sun [1]. Noting that gaseous envelopes may not reflect the Sun’s internal composition, Harkins [2] used analyses on 443 meteorites to conclude that Fe, O, Ni and Si are more abundant. B2FH [3] explained element synthesis in stars; decades later Fowler said laboratory and theoretical ...
متن کاملRelations between fusion cross sections and average angular momenta.
We study the relations between moments of fusion cross sections and averages of angular momentum. The role of the centrifugal barrier and the target deformation in determining the eeective barrier radius are clariied. A simple method for extracting average angular momentum from fusion cross sections is demonstrated using numerical examples as well as actual data.
