Resumen:

A first detailed study of the low-lying electronic states of the H 3 + molecular ion in linear configuration, parallel to a magnetic field, is carried out for B=0-4.414×1013 G in the Born-Oppenheimer approximation. The variational method is employed with a single, physically adequate trial function which includes, in particular, explicitly the electronic correlation term in the form exp?(? r 12), where ? is a variational parameter. The state of the lowest total energy (ground state) depends on the magnetic field strength. It evolves from spin-singlet 1? g for small magnetic fields B ? 5×108 G to weakly-bound spin-triplet 3? u for intermediate fields and eventually to spin-triplet 3? u state for B ? 5×10 10 G. © Springer Science+Business Media B.V. 2007.
