Is the $\lambda x^{-2}$ barrier penetrable?

Physically preferable self-adjoint expansion of a Hamiltonian with a property of $s(s+ 1)х^{-2}, — 1/2 < s < 1/2$ is selected. It is used to indicate a method for continuation through point $x=0$ of solutions of the Schr$\stackrel{..}{o}$edinger equation with a potential with the same property. After this standard rules are used to find the unambiguous coefficient of passage T of the $\lambda x^{-2}$ barrier (pit). In light of the uniformity of the Hamiltonian this coefficient in the absence of the additive barrier $h\delta (x)$ is not a function of energy. The coefficient T for a Coulomb barrier (pit) is cited.
