  The formation of composite particles in the electron liquid under QHE
conditions discussed by Jain in generalizing Laughlins many-particle state is
considered by using a model for two-dimensional guiding center configurations.
Describing the self-consistent field of electron repulsion by a negative
parabolic potential on effective centers and an inter-center amount we show
that with increasing magnetic field the ground state of so-called primary
composite particles $\nu=\frac{1}{q}$, $q=1,3,5,... $, is given for higher
negative quantum numbers of the total angular momentum. By clustering of
primary composite particles due to absorption or emission of flux quanta we
explain phenomenologically the quasi-particle structure behind the series of
relevant filling factors $\nu=\frac{p}{q}$, $p=1,2,3,...$.
  Our considerations show that the complicate interplay of electron-magnetic
field and electron-electron interactions in QHE systems may be understood in
terms of adding flux quanta $\Phi_0$ to charges $e$ and binding of charges by
flux quanta.
