Abstract
We study the excitation spectra and the dynamical structure factor of quantum Hall states in a finite-size system through exact diagonalizat ion. Comparison is made between the numerical results so obtained and the analytic results obtained from a modified random-phase approximati on in the preceding companion paper. We find good agreement between th e results at low energies.
