Abstract. Static and dynamic polarizabilities are calculated for the non-relativistic hydrogen molecular ion by solving the three-body Schrödinger equation in perimetric coordinates with the Lagrange-mesh method. The static dipole polarizabilities of the ground-state rotational band are computed for total orbital (or rotational) angular momenta from L = 0 to 39 with an absolute accuracy of about 10 −9 atomic units. For L = 0, 1 and 2, slightly less accurate results are also given for the first three vibrational excited levels. For the ground state, dynamic dipole polarizabilities as well as static and dynamic quadrupole polarizabilities are computed. To illustrate the versatility of the method, the static dipole polarizability of the hydrogen molecular ion in a Debye plasma is also determined.

“…On the other hand the experimental value for the dipole polarizability has been deduced from the effective model Hamiltonian [11] which is a fully nonrelativistic Hamiltonian and it does not include the retardation Casimir-Polder effect [12] for the Rydberg electron. On the importance of this phenomena has been pointed out in a paper of Babb and Spruch [13].…”

The recently reported precise experimental determination of the dipole polarizability of the H + 2 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 0.0007a 3 0 , 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 H + 2 molecular ion. Our conclusion is that it accounts for only 1/5 of the measured discrepancy.

“…Using microwave spectroscopy, Lundeen and coworkers have measured high-resolution spectra of nonpenetrating high l states. 14,15 Hyperfine structure in low l states of very high n-Rydberg states has been recently reported in a beautiful series of experiments. 16 The electronic structure of molecular hydrogen results in dynamics, which differs strongly for different symmetries and multiplicities.…”

We present single-photon spectroscopy in molecular hydrogen starting from the metastable c 3 ⌸ u Ϫ state to a number of triplet nd-Rydberg states (vϭ0 -4, nϭ12-20). Using fast beam spectroscopy both the autoionization channel and the predissociation channel are quantified, field free, as well as with small electric fields. Coupling with the i 3 ⌸ g state is assumed to be responsible for field-free predissociation of the vϭ0 Rydberg levels. The stronger observed predissociation channel of the vϭ1 Rydberg levels is due to the nonadiabatic interaction with the h 3 ⌺ g ϩ state in combination with l mixing due to an external electric field. No direct evidence is found for possible electric field induced predissociation of the gerade Rydberg states by low lying ungerade states. The competition between autoionization and predissociation is discussed in terms of possible consequences for dissociative recombination involving low energy electron collisions with the H 2 ϩ molecular ion.
