Simultaneous Measurements of Analyzing Powers and Differential Cross Sections for n+28Si

Scattering experiments conducted with beams of polarized neutrons give special information about the spin sensitive part of the neutron-nucleus interaction. Carefully controlled measurements of the analyzing power A(θ) for the scattering of polarized neutron beams can also give accurate values for the more conventional observable, the differential cross section σ(θ). The present paper focuses on an attempt to obtain σ(θ) values for 28Si(n,n) from an experiment originally intended to determine only the function A(θ). As a test the data are compared to cross sections measured in a conventional neutron scattering experiment.
