Neutron scattering

Definition

Neutron scattering is a technique used to investigate the atomic and molecular structure of materials by observing the scattering of neutrons after they interact with the sample. This method is particularly useful in studying materials at the atomic scale, revealing insights about molecular dynamics, phase transitions, and even the properties of soil-water interactions that influence plant growth.
