✦ Synopsis

After a short overview of the methods applied for measuring the neutron-skin thickness, we present the recent experimental results for the neutron-skin thicknesses of the 112-124Sn even-even isotopes and of "'Pb

We have used inelastic alpha scattering to excite the giant dipole resonance (GDR). The cross section of this process depends strongly on L1R,/R, the relative neutron-skin thickness.

We have also measured the excitation of the spin-dipole resonance (SDR) t o e d d uce the neutron-skin thickness since the summed L=l strength of the SDR is sensitive to it. The results obtained are in good agreement with the previous experimental and theoretical ones.
