  Bidimensional muonic and electronic atoms, with nuclei composed of a proton,
deuteron, and triton, and governed by Chern-Simons potential, are numerically
solved. Their eigenvalues and eigenfunctions are determined with a slightly
modified Numerov method. Results are compared with those assuming that the same
atoms are governed by the usual $1/r$ potential even in a two-dimensional
space, as well as with its three-dimensional analogs.
