Abstract
A simple model of disorder in fractional quantum Hall systems is combined with the standard exact diagonalisation technique. Electron-density--dependent gaps at filling factors 1/3,2/3,2/5, and 3/5 measured by activated transport can then be fitted with a single reasonable value of d which has the meaning of the separation of ionized donors from the quasi-2D electron gas.
