Abstract
Pair-distribution functions g(r) of Laughlin quasielectrons (composite fermions in their second Landau level) are calculated in the fractional quantum Hall states at electron filling factors nu_e=4/11 and 3/8. A shoulder in g(r) is found, supporting the idea of cluster formation. The intra- and inter-cluster contributions to g(r) are identified, largely independent of nu_e. The average cluster sizes are estimated; pairs and triplets of quasielectrons are suggested at nu_e=4/11 and 3/8, respectively.
