Neutron Bounce Quantized in Earth Gravity
Scientists have used Earth's gravity to isolate quantum energy levels of the neutron for the first time. In an experiment at the Laue-Langevin Institute, carefully dropped neutrons appeared at discrete heights. This effect could help test how gravity affects neutrally charged particles of different masses.
