We present a split-beam neutron interferometric experiment to test the non-cyclic geometric phase tied to the spatial evolution of the system: the subjacent two-dimensional Hilbert space is spanned by the two possible paths in the interferometer and the evolution of the state is controlled by phase shifters and absorbers.
This is accomplished by positioning a quartz phase shifter across the two beams traversing the interferometer and rotating the angle, [delta], about the mounting axis.
