2025-12-04 Direct determination of the astrophysical reaction rate of 141Pr(γ,n)140Pr at the SSRF-SLEGS doi:10.57760/sciencedb.32822 en New measurement of 141Pr photoneutron cross section has been performed at the Shanghai Laser Electron Gamma Source (SLEGS) of the Shanghai Synchrotron Radiation Facility (SSRF) using quasi-monoenergetic laser Compton scattered (LCS) γ-ray beam. The cross section data of 141Pr(γ,n) was acquired using an unfolding iteration method with uncertainty less than 4%. The photodisintegration decay constants of 141Pr(γ,n) reaction for stellar temperatures between 0.2 GK to 10 GK are derived. 141Pr photoneutron cross section; Photodisintegration decay constant; SSRF-SLEGS Junheng Hu (胡竣恒) Zhendong An (安振东) Ting Liu (刘婷) PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset http://www.doi.org/10.1051/0004-6361/202558418 Science Data Bank
