The Oscillator Strengths of H2+, 1sσ_{g}-2pσ_{u}, 1sσ_{g}-2pπ_{u}

The oscillator strengths of the $H^+_2$ molecular ion, $1sσ_{g}-2pσ_{u}$, $1sσ_{g}-2pπ_{u}$ are calculated within the Born-Oppenheimer approximation. The variational expansion with randomly chosen exponents has been used for numerical studies. The oscillator strengths obtained for the transitions $1sσ_{g}-2pσ_{u}$, $1sσ_{g}-2pπ_{u}$ of $H^+_2$ are accurate up to ten significant digits. Results are given for the internuclear distances between 0.10 and 20.0 a.u.

Static Dipole Polarizability for the $1Sσ$ electronic state of the $H^+_2$ molecular ion

The static dipole polarizabibility for the $1sσ$ electron state of the $\mathrm{H}_{2}^{+}$ hydrogen molecular ion is calculated within Born-Oppenheimer approximation. The variational expansion with randomly chosen exponents has been used for numerical studies. The results obtained for the dipole polarizability are accurate to the nine digits.

Relativistic corrections of order mα^6 to the two-center problem

Effective potentials of the relativistic mα^6 order correction for the ground state of the Coulomb two-center problem are calculated. They can be used to evaluate the relativistic contribution of that order to the energies of hydrogen molecular ions or metastable states of the antiprotonic helium atom, where precision spectroscopic data are available. In our studies we use the variational expansion based on randomly chosen exponents that permits to achieve high numerical accuracy.
