    "abstract": "The rate of phase-space exploration in the decay of isovector and isoscalar\ngiant quadrupole resonances in $^{40}$Ca is analyzed. The study is based on the\ntime dependence of the survival probability and of the spectrum of generalized\nentropies evaluated in the space of 1p-1h and 2p-2h states. If the 2p-2h\nbackground shows the characteristics typical for chaotic systems, the isovector\nexcitation evolves almost statistically while the isoscalar excitation remains\nlargely localized, even though it penetrates the whole available phase space.",
