摘要

The 14C(n, γ)15C reaction plays an important role in various astrophysical scenarios: (1) it is the slowest in the neutron induced CNO cycle which occurs in asymptotic giant branch (AGB) stars, and therefore controls this cycle [1];(2) it is one of the key reactions for predicting the primordial abundances of the heavy elements in the framework of inhomogeneous big-bang nucleosynthesis (IBBN) [2];(3) it is also important for the synthesis of heavier isotopes in neutrino driven wind scenarios for the r-process in core-collapse supernova (i.e., Type-Ⅱ supernova) explosions [3-5].
