Abstract
The low-lying energy spectra of five quark systems (I=1/2, S=0) and (I=0, S=-1) are investigated with three kinds of schematic interactions: the chromomagnetic interaction, the flavor-spin dependent interaction and the instanton-induced interaction. In all the three models, the lowest five quark state ( or ) has an orbital angular momentum L=0 and the spin-parity ; the mass of the lowest state is heavier than the lowest state.
