摘要：

We discuss exclusion statistics parameters for quasiholes and quasielectrons excited above the fractional quantum Hall states near nu=p/(2np+1). We derive the diagonal statistics parameters from the (''unprojected'') composite fermion (CF) picture. We propose values for the off-diagonal (mutual) statistics parameters as a simple modification of those obtained from the unprojected CF picture, by analyzing finite system numerical spectra in the spherical geometry.
