In order to study the effect of the degree of deformation on the fusion reaction, we have researched for the fusion reaction of $$^{nat}$$Lu + $$^{16}$$O and $$^{165}$$Ho + $$^{20}$$Ne. In the systems, the projectile nucleus $$^{16}$$O is spherical, while $$^{20}$$Ne is deformed. Thus they are fusion reactions of deformed-spherical nuclei and deformed-deformed nuclei, respectively. Besides, latter system has the same compound nucleus, $$^{185}$$Ir, as the $$^{169}$$Tm + $$^{16}$$O reaction in previous work. The evaporation residue cross sections were measured by using a stack technique and a gas-jet technique for the projectile energies of 50 to 155 MeV. The cross sections were compared with the theoretical values calculated by HIVAP code. The measured excitation functions were found to agree fairly well with theoretical values. The results are consistent with the idea that the degree of deformation makes an effect on the rising edge of excitation functions near the Coulomb barrier.
