Abstract
We study the competitive γγ-decay of the
2
1
+
state of an even-even spherical nucleus. An influence of the phonon-phonon coupling on the double γ-decay width is analysed within the microscopic model based on the Skyrme energy density functional. It is shown that the γγ-decay width is sensitive to the interaction of the one- and two-phonon configurations of the giant dipole resonance.
