In the simplest example of scattering of two colliding particles with initial momenta $\backslash vec\_,\backslash vec\_$, resulting in final momenta $\backslash vec\_,\backslash vec\_$, the momentum transfer is given by :$\backslash vec\; q\; =\; \backslash vec\_\; -\; \backslash vec\_\; =\; \backslash vec\_\; -\; \backslash vec\_$ where the last identity expresses momentum conservation. Momentum transfer is an important quantity because $\backslash Delta\; x\; =\; \backslash hbar\; /\; |q|$ is a better measure for the typical distance resolution of the reaction than the momenta themselves. ==Wave mechanics and optics== A wave has a momentum $p\; =\; \backslash hbar\; k$ and is a vectorial quantity. The difference of the momentum of the scattered wave to the incident wave is called ''momentum transfer''. The wave number k is the absolute of the wave vector $k\; =\; q\; /\; \backslash hbar$ and is related to the wavelength $k\; =\; 2\backslash pi\; /\; \backslash lambda$. Often, momentum transfer is given in wavenumber units in reciprocal length $Q\; =\; k\_f\; -\; k\_i$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Momentum transfer」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
