摘要
We analyse a recently reported neutron interference experiment to measure a geometric phase and attempt to bring out the inadequacy of the ``phase modulo 2\pi" approach to the geometric phase. A modified neutron interferometer experiment to observe 2n\pi phase changes of topological origin resulting from closed circuits around singularities in the parameter space of the experiment is proposed.
