摘要：The 35 stable nuclei with the atomic number Z≥34 located at neutron deficient side of valley of
beta-stability are called as p-nuclei and are produced by so called p-process. P-process
nucleosynthesis proceeds mainly via a series of photon induced reactions (γ,n), (γ,p), and/or
(γ,α) in the astrophysical environment. A large reaction network involving thousands of reaction
rates is required to describe the p-process nucleosynthesis. Since, so far most of these reactions
are not accessible experimentally, these reaction rates mainly rely on the Hauser Feshbach
statistical model. Most γ-induced reactions are very difficult to measure directly. As alternative
methods, the charged particle induced cross sections can be measured by activation method and
on-line γ-detection method, and calculated from the inverse reaction cross sections using the
detailed balance theorem. Therefore, cross section measurements for proton and alpha induced
reactions are crucial for the p-process nucleosynthesis and for testing the recent statistical model
predictions of Hauser-Feshbach. The primary aim of this paper is to describe the status of
experimental cross section measurements of radiative charged particle capture reactions. The
experimental database obtained by activation method up to now and what can be done in the
future for the p-process are given.
