Abstract
The astrophysical p-process is an important way of nucleosynthesis to produce the stable and proton-rich nuclei beyond Fe which can not be reached by the s- and r-processes. In the present study, the astrophysical reaction rates of (γ,n), (γ,p), and (γ,α) reactions are computed within the modern reaction code TALYS for about 3000 stable and proton-rich nuclei with 12 Ru(γ,p) and 96 Ru(γ,α) are performed. It is shown that the experiments of photonuclear reactions in p-process based on ELI-NP are quite promising.
Highlights
In massive star evolution and stellar explosive site, the astrophysical p-process is an important way of nucleosynthesis to produce the stable and proton-rich nuclei beyond Fe which cannot be reached by the s- and r-processes
We perform the systematic computations of (γ,n), (γ,p), and (γ, α) reaction rates on a e-mail: yi.xu@eli-np.ro about 3000 nuclei based on the TALYS software with the specific nuclear structure ingredients
The photonuclear reaction rates of (γ,n), (γ,p), and (γ, α) on about 3000 stable and proton-rich nuclei are computed with the help of TALYS, which is a software for the simulation of nuclear reactions [3, 4]
Summary
In massive star evolution and stellar explosive site, the astrophysical p-process is an important way of nucleosynthesis to produce the stable and proton-rich nuclei beyond Fe which cannot be reached by the s- and r-processes. To completely determine the nucleosynthesis of p-process, accurate knowledge of capture and photodisintegration reaction rates for about 3000 stable and protonrich nuclei is essential.
