Expressions are presented for the modification due to the nuclear potential apart from the Coulomb potential both for the eikonal and the noneikonal trajectories. Calculations for heavy ion total reaction cross sections are performed using these expressions. Results are given for several systems. It is found that the expression used by Cha leads to unrealistic values for the distance of closest approach at small impact parameters at low energies and therefore lead to inaccurate values of the total reaction cross section. The exactly calculated distance of closest approach leads to improved results both for the eikonal and the noneikonal trajectories. PACS number(s): 25.70.Bc, 24. 10.Ht

“…4 The CC effects in this system should be pronounced and appreciably influence on the fusion channel. Since the neighboring systems of 16 O + 208 Pb and 16 O + 209 Bi are well investigated, [5][6][7] it is interesting to make a comparison with these systems. Furthermore, the fusion data of 19 F + 208 Pb system are available in the literatures.…”

Angular distributions of elastic scatterings for 19 F + 208 Pb system have been measured at six energies around the Coulomb barrier. It is found that the real and imaginary potentials show pronounced energy dependence in terms of the phenomenological optical model analysis. The real parts of potentials extracted from the fusion data are similar to those from the elastic data. A comparison with the neighbouring systems of 16 O + 208 Pb and 16 O + 209 Bi reveals that the 19 F deformations play an important role in the fusion reaction. Based on the deformed and energy dependent barrier penetration model, the calculated fusion cross sections and mean-square spin distribution agree with the experimental data well. Moreover, it is indicated that the enhancement of fusion cross sections attributes to the dynamic polarization effects around the barrier, and to the static deformation effects further below the barrier.
