The Jinping Underground experiment for Nuclear Astrophysics (JUNA) takes advantage of the ultra-low background of the CJPL to conduct experiments for directly studying crucial reactions at stellar energies in the evolution of stars. In 2020, JUNA commissioned a mA level high current accelerator based on an ECR source, as well as high efficiency BGO and 3He detectors. Direct measurements of key nuclear reactions, including , , , and , were performed in JUNA with improved precision and closer to the Gamow window relative to previous measurements. These precise reaction rates provide valuable insights into the high precision astrophysics simulation.
期刊介绍：
Nuclear Physics A focuses on the domain of nuclear and hadronic physics and includes the following subsections: Nuclear Structure and Dynamics; Intermediate and High Energy Heavy Ion Physics; Hadronic Physics; Electromagnetic and Weak Interactions; Nuclear Astrophysics. The emphasis is on original research papers. A number of carefully selected and reviewed conference proceedings are published as an integral part of the journal.
