Radiative decays of basic scalar, vector and tensor mesons and the determination of the P-wave q\bar q multiplet
We perform simultaneous calculations of the radiative decays of scalar mesons
f_0(980)-> \gamma\gamma, a_0(980)-> \gamma\gamma, 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)-> \gamma\gamma, f_2(1270)-> \gamma\gamma, f_2(1525)->
\gamma\gamma assuming all these states to be dominantly the q\bar 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 q\bar q multiplet.Comment: 28 pages, LaTeX, 9 PostScript figures, epsfig.st
