Abstract. We investigate the interaction of O+
ions with a one-dimensional potential well, using Hamiltonian formulation.
Heating of plasma originating in the terrestrial ionosphere plays a catalytic role in solar-driven magnetic storms, which dis-
sipate energy globally within the magnetosphere of the earth. An interesting candidate for ionospheric plasma heating is a
potential well located at auroral arcs in the high-latitude magnetosphere. We consider a potential with an exponential form,
