A computer simulation is performed to study localization in a two-dimensionalelectron system in strong magnetic fields. When scatterers only with attractivepotentials are present and their concentration is not so high, the density of statesis not symmetric around the center of each Landau level. The energy of delocalizedstates in this case is shown to be close to the energy where the real part of Green'sfunction vanishes except in the case of extremely low concentrations of scatterers.Effects of mixings between different Landau levels are also studied by includinga finite number of Landau levels. It is shown that extended states remain to bepresent even if level mixings arc important and that the energy for extendedstates is shifted to the higher energy side with the decrease of the strength of themagnetic field.
