A12 (2001) 103115  Subject:  hepph  Abstract:  We perform simultaneous calculations of the radiative decays of scalar mesons f_0(980)> gammagamma, a_0(980)> gammagamma, vector meson phi(1020)> gamma f_0(980), gamma a_0(980), gamma pi^0, gamma eta, gamma eta’ and tensor mesons a_2(1320)> gammagamma, f_2(1270)> gammagamma, f_2(1525)> gammagamma assuming all these states to be dominantly the qar q ones. A good description of the considered radiative decays is reached by using almost the same radial wave functions for scalar and tensor mesons that supports the idea for the f_0(980), a_0(980) and a_2(1320), f_2(1270), f_2(1525) to belong to the same P wave qar q multiplet.
