G. V. Efimov

摘要:

利用定态薛定谔方程得到了弹性散射振幅的路径积分表示。给出了计算大耦合常数路径积分的几种方法。该方法是基于不确定性相关。计算了直角势、奇异势和汤川势的散射长度和截面。与精确结果进行了比较。

英文摘要:

Representation of the elastic scattering amplitude in the form of the path integral is obtained using the stationary Schroedinger equation. A few methods of evaluation of path integrals for large coupling constants are formulated. The methods are based on the uncertainty correlation. The scattering lengths and cross sections are calculated for the right angled and singular potentials and the Yukawa potential. The comparison with exact results is made.
