Penetration Factor for Nuclear Fusion Reaction in Nonthermal Astrophysical Plasmas

Nuclear astrophysical plasmas: ion distribution functions and fusion rates

This article illustrates how very small deviations from the Maxwellian exponential tail, while leaving unchanged bulk quantities, can yield dramatic effects on fusion reaction rates and discuss several mechanisms that can cause such deviations. Fusion reactions are the fundamental energy source of stars and play important roles in most astrophysical contexts. Since the beginning of quantum mech...

Nuclear Excitation Processes in Astrophysical Plasmas

Fusion Rates in Nuclear Plasmas

Energy and momentum of the elementary excitations become independent variables in medium: energy and momentum statistical distributions are not identical. The momentum distribution and not the energy distribution is relevant for barrier penetration. The deviations of the momentum distribution from the MaxwellBoltzmann energy distribution can be expressed in terms of the imaginary part of the se...

Astrophysical Reaction Rates as a Challenge for Nuclear Reaction Theory

The relevant energy ranges for stellar nuclear reactions are introduced. Low-energy compound and direct reactions are discussed. Stellar modifications of the cross sections are presented. Implications for experiments are outlined.
