| 英文摘要 | Fluorine is one of the most interesting elements in nuclear astrophysics, where the F-19(p, alpha gamma)O-16 reaction is of crucial importance for Galactic F-19 abundances and CNO cycle loss in first generation Population III stars. As a day-one campaign at the Jinping Underground Nuclear Astrophysics experimental facility, we report direct measurements of the essential F-19(p, alpha gamma)O-16 reaction channel. The gamma-ray yields were measured over E-c.m. = 72.4-344 keV, covering the Gamow window; our energy of 72.4 keV is unprecedentedly low, reported here for the first time. The experiment was performed under the extremely low cosmic-rayinduced background environment of the China JinPing Underground Laboratory, one of the deepest underground laboratories in the world. The present low-energy S factors deviate significantly from previous theoretical predictions, and the uncertainties are significantly reduced. The thermonuclear F-19(p, alpha gamma)O-16 reaction rate has been determined directly at the relevant astrophysical energies. |
