Few-body Decay and Recombination in Nuclear Astrophysics

摘要

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 α decay in connection with 2+ resonances and density and temperature dependence rates of recombination into light nuclei from α-particles and neutrons.
