摘要：

In nuclear astrophysics, 141Pr is mainly produced by an s process, which has a neutron magic number (N = 82) leading to its low capture cross section and strongly affecting the s process. Its neutron capture cross section is an important input parameter for nuclear astrophysical network calculations. According to the EXFOR database, the measurement precision for the 141Pr(n, gamma) cross section should be improved in the resolved and unresolved reso-nance region. The (n, gamma) cross section of 141Pr was measured between 1 eV and 500 keV at the Back-n facility of the Chinese Spallation Neutron...
