Abstract
We perform simultaneous calculations of the radiative decays of scalar mesons , , vector meson , , , , and tensor mesons , , , assuming all these states to be dominantly the 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 f0(980), a0(980) and a2(1320), f2(1270), f2(1525) to belong to the same P-wave multiplet.
