We present the elastic scattering angular distributions of the 9Be + 51V system measured at two energies near the Coulomb barrier, Elab = 17.44 and 18.53 MeV. The measurements were performed with the tandem Van de Graaff at the National Institute for Nuclear Research in Mexico. The theoretical analysis was made within the semimicroscopic optical model [1] that combines a microscopic calculation of the mean-field double folding potential and a phenomenological construction of the dynamical polarization potential. Calculations reproduced the elastic-scattering data very well and the total reaction cross sections were deduced. Comparison was made with the same calculations carried out using the Sao Paulo potential.
In order to check the consistency of our results with those for other systems with the same projectile (the left-hand panel of Fig. 1), we have compared our results with the data previously reported using a data reduction as proposed, for instance, in [2]. The reduced total reaction cross sections obtained for different systems having the same projectile show perfect consistency. On the other hand, our results are consistent with the reduced total reaction cross sections obtained for the other system, which has the 7Be isotope as a projectile. Thus we conclude that our results show a good agreement in comparison with the similar nuclear systems.
