摘要：

The differential cross section for the primordial reaction Li-8(p, n)Be-8(g.s.) has been determined at E(c.m.) = 1.5 MeV in the c.m. angular range 38-degrees to 90-degrees by use of the radioactive nuclear beam facility at the University of Notre Dame which utilizes a superconducting solenoid lens system designed at the University of Michigan, and a Be-8 detection technique developed at the Florida State University. A Li-8 beam of approximately 10(7) pps is used to infer a total cross section of 21+/-2 mb, with a 20% absolute cross section uncertainty. This total cross section is a factor of two smaller than a conventional Hauser-Feshbach calculation and it is also much smaller than that of some other Li-8 burning reactions.
