Abstract：
The targets of statically deformed nuclei ¹⁵²Sm and ¹⁸⁴W were bombarded by ¹⁶O beam and the excitation functions of quasi-elastic and elastic scatterings were measured at the backward angles. The barrier distributions, D ^qel(E) and D ^el(E) have been deduced from these excitation functions and compared with fusion barrier distributions extracted from existing fusion excitation function, spin distribution and the results of the experiments with neighboring isotope targets. The agreement is quite good. The calculatons of the D ^qel(E) and D ^el(E) with ECI79 code have already been porformed. It shows that the static deformation effect of target leads to the asymmetric barrier distributions.
