passing a neutron beam through a bottle filled up with this polarised gas lead to a final beam which is of one polarisation, even for a wide range of neutron wavelengths (white beam polarisation). Part-1: ... depends strongly on its ability of producing an intense and well-polarised neutron beam, and then of analyzing the diffracted beams. This is ...

of measuring very small rotations of the neutron polarisation. During this experiment, the neutron beam polarisation achieved by the filter was determined with high accuracy from spin dichroism measurements
