Neutron interferometric observation of the virtual excitation and multiple scattering correction terms to the index of refraction By aiming a light beam into any substantial body of liquid ethane or methane, the SSP will attempt to record the index of refraction of the fluid, another indication of its density. Motter points out that as the difference in the index of refraction between the polymer layers increases, fewer layers are needed to attain the necessary level of reflectivity. |
