[en] The non-relativistic S-wave spectrum of the q2q_2 system composed of u and d quarks is investigated in harmonic oscillator bases including all the configurations up to Nhw oscillator excitation energy with N <= 6 using a two-body interaction deduced from Bhaduri's potential. The lowest 2+ states are found near the rho/rho threshold and, in the same mass region, certain 0+ states are characterised by very small pi/pi components. These findings are consistent with bag model results and reinforce the multiquark interpretation of 0+ and 2+ resonances observed in P_/n annihilations and gamma/gamma reactions.
