Cp. Silva et al., FUSION AND PERIPHERAL PROCESSES IN THE O-16,O-18-58,NI-60,NI-64 SYSTEMS(NI), Physical review. C. Nuclear physics, 55(6), 1997, pp. 3155-3158
Fusion cross section measurements for the O-16,O-18 + Ni-58,Ni-60,Ni-6
4 systems, in the energy range 38 less than or equal to E(lab)less tha
n or equal to 64 MeV are presented, The standard radius deviations obt
ained from the data analysis, considering the zero-point motion of the
nuclear surface, are compared to those associated to quadrupole and p
airing vibration modes. Using the optical model analysis of the elasti
c data, the connection between the threshold anomaly and the subbarrie
r fusion enhancement is investigated.
