Abstract
For astrophysical calculations, it is customary to extrapolate higher-energy (≳20keV) data using the Gamow transmission coefficient in estimating the nonresonance nuclear fusion reaction cross sections σ(E) for charged particles at low energies (<20 keV). We present a general extrapolation method based on a more realistic Coulomb barrier transmission coefficient, which can accommodate simultaneously both nonresonance and resonance contributions.
