论文摘要
$ {}^{nat} pb（p，xn）{}^{}^{201-207} bi $，$ {}^{204} pb（p，1-4n）{}^{}^{201-204} bi $ $ $ $ $ $ {206} pb bi，天体物理能量范围$ 20-30 \，mev $。分析是通过与半衰期测量相关的$γ$ -SpectRoscopicy进行的。将结果与先前的实验数据（如果可用）进行了比较，并使用TALYS代码进行了理论计算。我们报告了可能的新$γ$从$ {}^{204M} {pb} $和其他理论差异的过渡，这可能是由于对库仑屏障和中子绑定能量的高估。还报告了在$ {}^{205,206} bi $衰减中发出的$γ$的能量和强度的新确定。我们讨论了超新星和中子星星合并中中微子驱动的风中R/RP过程的可能含义。
Cross-sections for ${}^{nat}Pb(p,xn){}^{201-207}Bi$, ${}^{204}Pb(p,1-4n){}^{201-204}Bi$ and ${}^{206}Pb(p,3n){}^{204}Bi$ reactions have been determined in the astrophysical energy range $20-30 \, MeV$. The analysis were performed by $γ$-spectroscopy associated with half-lives measurements. The results were compared with previously experimental data, when available, and with theoretical calculations performed using TALYS code. We report a possible new $γ$ transition from ${}^{204m}{Pb}$ and other theoretical discrepancies, probably due overestimation of the Coulomb barrier and neutron binding energy. Also reported are new determinations of the energies and intensities of the $γ$'s emitted in the decays of ${}^{205,206}Bi$. We discuss possible implications for the r/rp-processes in neutrino-driven wind in supernovae and neutron stars mergers.
