The elastic scattering for the ${}^{6,7}\mathrm{Li}+{}^{59}\mathrm{Co}$ systems was investigated in the bombarding energy range $12\text{MeV}⩽E_{\mathrm{lab}}⩽30\text{MeV}$ by means of an analysis using the São Paulo potential, through which the behavior of the real and imaginary parts as function of the bombarding energy was established. The experimental results suggest that overall there is an evidence of the usual threshold anomaly for both systems, although for the ${}^6\mathrm{Li}+{}^{59}\mathrm{Co}$ system, an evidence of the breakup threshold anomaly could also be questioned.
