The pygmy dipole states were populated in <sup>208</sup>Pb and <sup>124</sup>Sn by the inelastic scattering of a <sup>17</sup>O beam at the energy of 20 MeV/u, and their subsequent gamma decay was measured with the AGATA demonstrator array. Differential cross sections as a function of the angle were measured. The results are compared with (γ, γ') data. For the dipole transitions, a form factor obtained by folding a microscopically calculated transition density was used. This has allowed us to extract the isoscalar component of the 1<sup>-</sup> excited states.
