Fusion ofNi58,60,62with 113-170 MeVCa40ions

Results of measurements of the fusion excitation functions of ${}_{}{}^{58,60,62}{}_{}{}^{}\mathrm{Ni}$ targets with 113-170 MeV (lab) ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ ions are reported. These results are used to extract fusion barrier heights and radii by several different methods. Subbarrier fusion cross sections are analyzed in terms of static deformations. Possible importance of dynamic deformation is discussed. Conclusions as to the role of static deformation are similar to those from the ${}_{}{}^{35}{}_{}{}^{}\mathrm{Cl}$ + ${}_{}{}^{58,60,62}{}_{}{}^{}\mathrm{Ni}$ fusion system; a large part of the subbarrier behavior can be attributed to this cause.
