摘要：

The ground slate of a hydrogen molecule in magnetic fields is investigated using a fully numerical Hartree-Fock approach. We found that between 4.2x10(4) T and 3x10(6) T the ground state is (3) Sigma(u)(+) with very weak interaction between atoms. In this field region the hydrogen can form a superfluid phase, predicted earlier [Korolev and Liberman, Phys. Rev, Lett. 72, 270 (1994)]; the state 3 Pi(u) is metastable and may be responsible for the unknown excitonic line observed by Timofeev and Chernenko [JETP Lett 61, 617 (1995)]. For magnetic fields stronger than 3x10(6) T the ground state is the tightly bound (3) Pi(u).
