    "abstract": "Measured cross sections for the fusion of {64}Ni with {64}Ni, {74}Ge, and\n{100}Mo targets are analyzed in a coupled-channels approach. The data for the\n{64}Ni target above 0.1 mb are reproduced by including couplings to the\nlow-lying 2^+ and 3^- states and the mutual and two-phonon excitations of these\nstates. The calculations become more challenging as the fusing nuclei become\nsofter and heavier, and excitations to multi-phonon states start to play an\nincreasingly important role. Thus it is necessary to include up to four-phonon\nexcitations in order to reproduce the data for the {64}Ni+{74}Ge system.\nSimilar calculations for {64}Ni+{100}Mo, and also for the symmetric\n{74}Ge+{74}Ge system, show large discrepancies with the data. Possible ways to\nimprove the calculations are discussed.",
