Ion-molecular D 2 + complex in a quantum ring
Low-lying states of an ion-molecular D 2 + complex in quantum rings with different and small cross-sections are analyzed. Following the adiabatic procedure, we have deduced a one-dimensional wave equation with periodic conditions, which describes low-lying levels related to the electron rotation around the symmetric axis under the Coulomb interaction with the positive ions. We show that the strong confinement allow us to obtain artificial molecules more stable than the natural molecule.
