 Inclusive [$\Psi(\rm {2S})$/J/$\Psi$] ratio measured as a function of < $N_{\rm part}$> in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV for two $p_{\rm T}$ intervals, compared to NA50 results and to a theoretical calculation (left) Double ratio, as a function of $N_{\rm part}$, between the $\Psi(\rm {2S})$ and J/$\Psi$ measured in Pb-Pb at $\sqrt{s_{\rm NN}}=2.76$ TeV and pp collisions at $\sqrt{s}=7$ TeV, compared to theoretical calculations (right).
