| Abstract: | We present numerical results for the low-lying spectra of an electron confined in a magnetic quantum ring where the magnetic fields are zero inside the ring and constant elsewhere. Low-lying spectra for both on-center Coulomb acceptor and donor impurities, with qualitative aspects different from those without impurities doped, are also discussed. |
