prior to multipole decomposition. Cross sections for exciting the IVGDR were obtained with DWBA calculations on the basis of the Goldhaber-Teller model and using the strength distribution obtained from photonuclear work [55]. Figs. 7 and 8 show the MDA fits to the experimental angular distributions of the differ- ential cross sections for the 16.5-MeV and 25.5-MeV energy bins in the inelastic-scattering spectra of $^{112}$Sn and $^{124}$Sn, respectively, along with the contributions from the L =0, 1 and 2 multipoles. The ISGMR contribution is dominant in comparison to the other multipoles at E$_{x}$=16.5 MeV. On the other hand, the ISGDR is the dominant contributor at E$_{x}$=25.5 MeV. We have extracted strength distributions for L =0, 1, 2, and 3 multipoles over the energy range 8.5 MeV–31.5 MeV in all the Sn isotopes investigated in this work. These are displayed FIG. 7: Angular distribution of 1-MeV bins centered at E$_{x}$=16.5 MeV for $^{112}$Sn( α , α $^{′}$) and $^{124}$Sn( α , α $^{′}$). The solid squares are the experimental data and the solid lines are the MDA fits to the data. Also shown are the contributions to the fits from L =0 (dashed line), L =1 (dotted line), L =2 (dash-dotted line) and L =3 (small-dashed line) multipoles, as well as from the IVGDR (dash-dot-dotted line).
