摘要

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 β-decay studies and the determination of resonance parameters. The examples chosen are drawn from the experiments the author was involved in the last decade together with his group at Texas A&M University. One example discussed in particular is that of the reactions used to determine the S_(17) astrophysical factor for the ~7Be(p, γ)~8B reaction, crucial for the understanding the solar neutrino problem. We discuss also the case of the proton drip line nucleus ~(23)Al. From its study we extract data to determine the stellar reaction rates for ~(22)Mg(p, γ)~(23)Al and ~(22)Na(p, γ)~(23)Mg. Both breakup and beta-decay methods were used in these latter studies.
