AYGUN, M.; KOCADAG, O.  and  SAHIN, Y.. Phenomenological and microscopic model analysis of elastic scattering reactions of ¹⁸O by ²⁴Mg, ²⁸Si, ⁵⁸Ni, ⁶⁴Zn, ⁹⁰Zr, ¹²⁰Sn, and ²⁰⁸Pb target nuclei. Rev. mex. fis. [online]. 2015, vol.61, n.6, pp.414-420. ISSN 0035-001X.

In the present study, the optical potentials are obtained to describe the interactions of ¹⁸O at different incident energies. With this goal, the elastic scattering angular distribution data measured for many systems, ranging from ²⁴Mg to ²⁰⁸Pb are analyzed by using the phenomeno-logical model (PM) and the double folding model (DFM) within the framework of optical model (OM). It is presented that the theoretical results with the PM and the DFM are in very good agreement with both the experimental data and the results of previous studies. A new global set of imaginary potential of the double folding calculations is derived to describe the interactions of ¹⁸O at low energies. Also, the volume integrals of potentials, the cross sections and x²/N values obtained by means of the theoretical calculations for each system are given.
