The ^{13}C(α,n)^{16}O reaction is the main neutron source for slow-neutron-capture process in asymptotic giant branch stars and intermediate process. Direct measurements at astrophysical energies above-ground laboratories are hindered by extremely small cross sections vast cosmic-ray-induced background. We performed first consistent direct measurement range of E_{c.m.}=0.24 to 1.9 MeV using accelerators China Jinping Underground Laboratory Sichuan University. Our covers almost entire Gamow...
The solar composition problem has puzzled astrophysicists for more than 20 years. Recent measurements of carbon-nitrogen-oxygen (CNO) neutrinos by the Borexino experiment show a $\sim2\sigma$ tension with "low-metallicity" determinations. $^{14}$N$(p,\gamma)^{15}$O, slowest reaction in CNO cycle, plays crucial role standard model (SSM) calculations neutrino fluxes. Here we report direct measurement $^{14}$N$(p,\gamma)^{15}$O reaction, which $S$-factors all transitions were simultaneously...
