техника Фелла The Investigation of the Fine Shift to the Energy Levels in the Hydrogen–Like Atoms with Accuracy α^6 ln α^(-1) by Quasipotential Method Authors: Baykova N. A., Boikova O. A., Tyuhtyaev Y. N. In the quasipotential approach the quantity of Logarifmic corrections to the fine shift increased but the sum result of α^6 ln α^(-1) is equal zero. The past of high order to a corrections is calculated.
