Bound states around an impurity are investigated for a two-dimensional electron system in a strong magnetic field. Long-range Coulomb potential and related potentials are considered. The Schrodinger equation is solved numerically to obtain the bound states. The energy and wave function of these bound states are indirectly observed by scanning tunneling spectroscopy as the local density of states (LDOS). Theoretically obtained LDOS is compared with results of experiment. Reasonable agreement is obtained.
