Résumé : | The one-electron lithium-containing Coulomb systems of atomic type Li 2 + and molecular type Li5 +2, LiHe 4 + and LiH3 + are studied in the presence of a strong magnetic field B ≤ 107 au in a non-relativistic framework. They are considered at the Born-Oppenheimer approximation of zero order (infinitely massive centres) within the parallel configuration (molecular axis parallel to the magnetic field). The variational and Lagrange-mesh methods are employed, complementing each other. It is demonstrated that the molecular systems LiH 3 +, LiHe4 + and Li5 +2 can exist for sufficiently strong magnetic fields B ≳ 104 au and that Li5 +2 can even be stable at magnetic fields typical of magnetars. © 2010 IOP Publishing Ltd. |
