量子力学中势散射振幅的泛函积分方法

Functional integral method for potential scattering amplitude in quantum mechanics

Cao Thi Vi Ba, Do Thu Ha, Nguyen Nhu Xuan

摘要:

量子力学中的泛函积分方法可以用来求粒子在外场中的散射振幅。通过求解薛定谔方程,将质量壳上的极点分离后,由相应外场中的完全格林函数得到势散射振幅,在高能区和小散射角区,势散射振幅呈程函(Glauber)表示.考虑特定的外部势,如汤川势或高斯势,我们将找到相应的微分散射截面。

英文摘要:

The functional integral method can be used in quantum mechanics to find the scattering amplitude for particles in the external field. We will obtain the potential scattering amplitude form the complete Green function in the corresponding external field through solving the Schrodinger equation, after being separated from the poles on the mass shell, which takes the form of an eikonal (Glauber) representation in the high energy region and the small scattering angles. Consider specific external potentials such as the Yukawa or Gaussian potential, we will find the corresponding differential scattering cross-sections.
