Confinement, chiral dynamics and light scalar mesons. 2. $ϕ$-meson radiative decays about nature of light scalar resonances. Arguments in favor of the four-quark model of the $a_0(980)$ and $f_0(980)$ mesons are given.9 pages, 3 figures, Talk given on May 28, 2004 at QUARK-2004, May 24-30, 2004, Pushkinskie Gory, Pskovskaya region, RussiaHigh Energy Physics - PhenomenologyHigh Energy Physics - ExperimentNuclear Theorytext
