Higher Order Structural Relativistic Effects for s-States of Hydrogen-Like Systems

Abstract

A calculation of structural relativistic corrections of higher orders for the ground states of hydrogen-like systems, such as a hydrogen atom and a muonic hydrogen atom, has been performed. The dependence of the corrections on the parametrization of proton form factors is investigated. The numerical estimates show that the corrections are within the limits of sensitivity of modern experiments to measure the energy characteristics of hydrogen-like systems.
