Elastic scattering of polarized neutrons on O16, Co59, and Pb at 23 MeV

Differential cross sections and analyzing powers of neutrons elastically scattered from O16, Co59, and Pb were measured using two 183 cm long position sensitive scintillators. A beam of polarized neutrons (P=0.51, En=23 MeV) was produced by the H3(d,n)4He reaction. A superconducting solenoid was used to precess the neutron spin by 180°for the determination of analyzing powers. After correcting for neutron flux attenuation and multiple scattering due to the finite size of the scatterers, the data were analyzed using a conventional optical model potential. © 1985 The American Physical Society.
