摘要The abundance patterns of neutron-capture elements in very metal-poor halo stars play a crucial role in guiding and constraining theoretical models of nucleosynthesis. Many studies have suggested that the abundance patterns of the heavier (Zgreater than or equal to 56) stable neutron-capture elements in very metal-poor halo stars are consistent with the solar system r-process abundance distribution, but this concordance breaks down for the lighter neutron-capture elements in the range of 40
