The reflection width of perfect silicon crystals for thermal neutrons and the Zeeman splitting (ΔE = 2μB) of a field of about 10 kGs are comparable and therefore can be used to polarize a neutron beam. For a monochromatic beam (energy ![[E_{0}]](/teximages/bach3o3/bach3o3fi142.svg)
) in a strong magnetic field region, the result of the Zeeman splitting will be a separation into two polarized subbeams, one polarized along B with energy E0 + μB, and the other polarized antiparallel to B with energy E0 − μB. The two polarized beams can be selected by rocking a perfect crystal in the field region B (Forte & Zeyen, 1989![[link]](/graphics/greenarr.gif)
).
