The radiative transitions between ground-states of light qq-bar mesons are investigated in the U-tilde(12)-classification scheme. In this scheme the rich decay-spectra are offered even in transition between ground states due to the appearance of 'chiral states', out of the framework of non-relativistic quark model(NRQM) based on the SU(6)-symmetry, and it is shown that these states play an important role to improve our previous results, obtained without considering them.
