Abstract

The differential cross section for the primordial reaction ${}^{8}{Li}$ (p,n $)^{8}$ Be(g.s.) has been determined at $E_{c . m .}$ =1.5 MeV in the c.m. angular range 38° to 90° 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 ${}^{8}{Be}$ detection technique developed at the Florida State University. A ${}^{8}{Li}$ 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 ${}^{8}{Li}$ burning reactions.
