Compton Scattering Equation康普顿散射方程
![]() In his explanation of the Compton scattering experiment, Arthur Compton treated the x-ray photons as particles and applied conservation of energy and conservation of momentum to the collision of a photon with a stationary electron. Using the Planck relationship and the relativistic energy expression, conservation of energy takes the form 在解释康普顿散射实验时,阿瑟·康普顿将X射线光子视为粒子,并将光子与静止电子的碰撞中的能量守恒和动量守恒应用于该碰撞。利用普朗克关系式和相对论能量表达式,能量守恒的形式为
![]() Conservation of momentum requires 动量守恒要求
![]() where p=E/c is used for the photon momentum. Squaring this equation using the scalar product gives 其中使用 p=E/c 表示光子的动量。用标量积对这个方程平方得到
![]() Again using the Planck relationship and the relativistic energy expression: 再次利用普朗克关系和相对论能量表达式:
![]() The energy conservation expression above can be squared to give 上述能量守恒表达式平方后可得到
![]() These two forms can be equated to give 这两种形式可以相等以得到
![]() which can be rearranged to 这可以重新排列为
![]() and finally to the standard Compton formula: 最后得到标准的康普顿公式:
![]()
