Solid curves are angle-dependent neutron spectra escaping from the Sun (prior to any neutron decay) for a downward-isotropic interacting-ion angular distribution (δ = 0 and ﹩\lambda \to \infty ﹩), shown for several direction angles ψ_n. The dashed curve is the angle-integrated neutron spectrum at production within the solar atmosphere. The gray band identifies the 30–100 keV energy range.
