Coulomb displacement energy and the lowenergy astrophysical S_{17} factor for the ^{7}Be(p,γ) ^{8}B reaction
Abstract
The relationship between the Coulomb displacement energy for the A = 8, J = 2 ^{+}, T = 1 state and the lowenergy astrophysical S_{17} factor for the ^{7}Be(p,γ) ^{8}B reaction is discussed. The displacement energy is interpreted in a particlehole model. The dependence of the particle displacement energy on the potential well geometry is investigated and is used to relate the particle displacement energy to the rms radius and the asymptotic normalization of the valence proton wave function in ^{8}B. The asymptotic normalization is used to calculate the astrophysical S_{17} factor for the ^{7}Be(p,γ) reaction. The relationship to the ^{7}Li(n,γ) reaction, the ^{8}B quadrupole moment, radial density, and breakup momentum distribution are also discussed.
