Momentum Transfer

In particle physics, wave mechanics and optics, momentum transfer is the amount of momentum that one particle gives to another particle.

In the simplest example of scattering of two colliding particles with initial momenta, resulting in final momenta, the momentum transfer is given by

where the last identity expresses momentum conservation. Momentum transfer is an important quantity because is a better measure for the typical distance resolution of the reaction than the momenta themselves.

Famous quotes containing the word transfer:

    If it had not been for storytelling, the black family would not have survived. It was the responsibility of the Uncle Remus types to transfer philosophies, attitudes, values, and advice, by way of storytelling using creatures in the woods as symbols.
