Indirect techniques in nuclear astrophysics: a review.
In this review, we discuss the present status of three indirect techniques that are used to determine reaction rates for stellar burning processes, asymptotic normalization coefficients, the Trojan Horse method and Coulomb dissociation. A comprehensive review of the theory behind each of these techniques is presented. This is followed by an overview of the experiments that have been carried out...
متن کاملNuclear Astrophysics with Radioactive Nuclear Beams: Indirect Methods
The review describes a number of indirect methods in nuclear astrophysics using radioactive beams: Coulomb dissociation, transfer reactions (the ANC method), breakup of loosely bound nuclei at intermediate energies, the use other spectroscopic measurements, including -decay studies and the determination of resonance parameters. The examples chosen are drawn from the experiments the author was i...
متن کاملIndirect Techniques in Nuclear Astrophysics: Asymptotic Normalization Coefficients and the Trojan Horse Method
Both direct and indirect techniques have been used for many years to determine nuclear reaction rates at astrophysical energies. A number of problems have been encountered which limit measurements by direct techniques, including very low cross sections, the importance of subthreshold states and the need for radioactive targets. Over the past decade, new indirect techniques have been developed t...
متن کاملNuclear Problems in Astrophysics
These lectures, presented at the International School of Physics " Enrico Fermi, " deal with two major themes. The first is the remarkable story of the solar neu-trino problem, which (along with the atmospheric neutrino anomaly) recently led to the discovery of massive neutrinos and neutrino oscillations, physics beyond the standard model. I will describe the physics of the standard solar model...
متن کاملGenerating Process Explanations in Nuclear Astrophysics Generating Explanations in Astrophysics
In this paper we describe ASTRA, a computational aid for generating process explanations in nuclear astrophysics. The system operates in two stages, the rst using knowledge of quantum theory to produce a set of legal reactions among elements and the second searching for pathways of such reactions that explain the evolution of some element in terms of lighter ones. ASTRA has found apparently nov...
