标题： NUCLEAR ASTROPHYSICS WITH SECONDARY (RADIOACTIVE) BEAMS

摘要： 一些核天体物理问题被讨论，重点是过去二十年未解决的该领域核心问题，包括大质量恒星中的氦燃烧（12C(α,γ)16O反应）和8B太阳中微子通量问题（7Be(p,γ)8B反应）。 我们证明通过测量时间反演过程：16N的β延迟α粒子发射和8B的库仑分离，使用放射性束（16N和8B）取得了很大进展。 这样实现了所需截面的放大，使得能够测量与恒星（太阳）过程相关的微小截面。 显示英文摘要

摘要： Some problems in nuclear astrophysics are discussed with emphasize on the ones central to the field which were not solved over the last two decades, including Helium Burning in Massive stars (the 12C(a,g)16O reaction) and the 8B Solar Neutrino Flux Problem (the 7Be(p,g)8B reaction). We demonstrate that a great deal of progress was achieved by measuring the time reverse process(es): the beta-delayed alpha-particle emission of 16N and the Coulomb dissociation of 8B, using radioactive beams (of 16N and 8B). In this way an amplification of the sought for cross section was achieved, allowing a measurement of the small cross section(s) of relevance for stellar (solar) process(es).
