评"δ函数势的维数展开“
Comment on `Dimensional expansion for the delta-function potential'
摘要:
我批评了最近一篇文章[C. M. Bender和L. R.米德,欧洲J.Phys.20,117(1999)],为了获得从二维δ函数势散射的正确截面,必须在空间维中进行解析延拓。
英文摘要:
I criticize the claim, made in a recent article [C. M. Bender and L. R. Mead, Eur. J. Phys. 20, 117 (1999)], that in order to obtain the correct cross section for the scattering from a two-dimensional delta-function potential one must perform analytic continuation in the dimension of space.
