Aharonov–Bohm and gravity experiments with the very-cold-neutron interferometer

We report on the specific techniques associated with experiments with the interferometer for very-cold neutrons at the Institute Laue-Langevin (ILL). Two recent experiments are presented: one to measure the gravitational phase shift to high precision and one to demonstrate the non-dispersivity of the scalar Aharonov–Bohm effect for neutrons.
