Abstract The influence of a constant magnetic field on the energy of the ground state of an exciton bound to a neutral shallow impurity is studied in the high field limit. The Schrödinger equation is solved using the adiabatic approximation and considering the Coulomb potential as a perturbation with respect to the fundamental Landau level. The total energy is calculated by means of a combination of four Gaussian type variational wave functions. The results show that the magnetic field enhances the Coulomb interaction and allow to estimate the transition energies.
