Abstract

We discuss in detail the coupled-channels approach for large-angle quasi-elastic scattering in massive systems, where many degrees of freedom may be involved in the reaction. We especially investigate the effects of single-, double-, and triple-phonon excitations on the quasi-elastic scattering for Ti48, Cr54, Fe56, Ni64, and Zn70+Pb208 systems, for which the experimental cross sections have been measured recently. We show that the present coupled-channels calculations well account for the overall width of the experimental barrier distribution for these systems. In particular, it is shown that the calculations taking into account single-quadrupole phonon excitation in Ti48 and triple-octupole phonon excitations in Pb208 reasonably well reproduce the experimental quasi-elastic cross section and barrier distribution for the Ti48+Pb208 reaction. However, Cr54, Fe56, Ni64, and Zn70+Pb208 systems seem to require the double-quadrupole phonon excitations in the projectiles to reproduce the experimental data.
