Two component, or pseudospin 172, fermion system in the lowest Landau level isinvestigated. The ground state at V=2/5, where v is the filling factor of the lowestLandau level, has quite different character from that of v = 1/3 : In the former thetotal pseudospin is zero, while in the latter pseudospin is fully polarized. The excita-tion spectrum from these qualitatively different ground states are investigatednumerically at small but finite momentum. The quasiparticles for these ground statesare also investigated, and existence of those with charge "re/5 at v=2/5 is shown.The knowledge of the quasiparticle charge makes extrapolation of the numericalresults to infinite momentum possible, and activation energies are obtained.
