   • 2015, K. Hagino, N. Rowley, J.M. Yao, “Recent developments in heavy-ion fusion reactions around the Coulomb barrier”, in arXiv‎:

     We apply this method to subbarrier fusion reactions of ${\displaystyle ^{58}}$Ni+${\displaystyle ^{58}}$Ni and ${\displaystyle ^{40}}$Ca+${\displaystyle ^{58}}$Ni systems, and discuss the role of anharmonicity of the low-lying vibrational motions..
