Relativistic corrections to the dipole polarizability of the ground state of the molecular ion H2+

Abstract
The recently reported precise experimental determination of the dipole polarizability of the H2+ molecular ion ground state [P.L. Jacobson, R.A. Komara, W.G. Sturrus, and S.R. Lundeen, Phys. Rev. A 62, 012509 (2000)] reveals a discrepancy between theory and experiment of about 0.0007a03, which has been attributed to relativistic and QED effects. In present work we analyze an influence of the relativistic effects on the scalar dipole polarizability of an isolated H2+ molecular ion. Our conclusion is that it accounts for only 1/5 of the measured discrepancy.
