The history of experimental study on β -delayed proton decays in the rare-earth region was simply reviewed. The physical results of the β -delayed proton decays obtained at IMP, Lanzhou over the last 10 years were summarized, mainly including the first observation of 9 new β -delayed proton precursors along the odd-Z proton drip line and the new data for 2 waiting-point nuclei in the rp-process. The results were compared and discussed with different nuclear model calculations. Finally, the perspective in near future was briefly introduced. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]

A method, neutron transfer reaction and charge symmetry of mirror nuclei, is used to study (p,γ) reaction on proton-rich nuclei in this paper. The asymptotic normalization coefficients (ANCs) of virtual decays 9Li → 8Li + n and 27Mg → 26Mg + n were extracted from the angular distributions of the 8Li(d, p)9Li and 26Mg(d, p)27Mg reactions, through distorted wave Born approximation (DWBA) analysis. The astrophysical S-factors and reaction rates of 8B(p, γ)9C and 26Si(p, γ)27P were then determined based on charge symmetry. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
