摘要：

A model is presented to investigate the systematics of in-situ low-energy neutron-capture-produced cosmogenic nuclides in terrestrial rocks, in particular Cl-35(n,gamma)Cl-36, by using a Monte Carlo neutron transport code. The model is validated by comparison of its results with experimental measurements of low-energy cosmogenic neutrons on the Earth's surface. The dependence of Cl-36 production on the elemental composition and water content of rocks has been determined.
