15 صفحه اولComment on ‘ Dimensional expansion for the delta - function potential ’
I criticize the claim, made in a recent article (Bender C M and Mead L R 1999 Eur. J. Phys. 20 117–21), 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. In a recent paper Bender and Mead [1] obtained the total cross section for the scattering from an attractive d...
