Few-body decay and recombination in nuclear astrophysics

Abstract

Three-body continuum problems are investigated for light nuclei of astrophysical relevance. We focus on three-body decays of resonances or recombination via resonances or the continuum background. The concepts of widths, decay mechanisms and dynamic evolution are discussed. We also discuss results for the triple $\alpha$ decay in connection with $2^{+}$ resonances and density and temperature dependence rates of recombination into light nuclei from $\alpha$-particles and neutrons.
