H-2(-FIELD - A VARIATIONAL STUDY() ION IN STRONG MAGNETIC)

Using a single trial function, we perform an accurate calculation of t he ground state 1 sigma(g) of the hydrogenic molecular ion H-2(+) in a constant uniform magnetic field ranging from 0 to 10(13) G. We show t hat this trial function also makes it possible to study the negative p arity ground state 1 sigma(u). We show that, over the whole range of m agnetic fields studied the calculated binding energies are in most cas es larger than binding energies obtained previously by other authors u sing different methods.
