Angular correlation for deep inelastic processes in 19 F + 27 Al collision in the energy range (116.75 - 122.25) MeV

The excitation function for 19 F + 27 Al in the energy interval Elab = (113.5 - 130) MeV with an increment of 250 keV has been measured using experimental device DRACULA. The main component of the experimental device DRACULA are two large area position sensitive ionization chambers (IC). The IC was centred at 27 angle covering an angular range of θ = [15 angle - 39 angle] for each incident energy. Though the experiment was not designed for an angular correlation analysis the large angular coverage makes it possible and such an analysis is presently in progress. In the literature there exists scarce results in this domain. Preliminary results of this analysis are presented in this contribution. Excitation functions in the energy interval (116.75 - 122.25) MeV for θcm step of 2 angle, for fragments with Z = 6 - 8, 10 with the total kinetic energy loss, TKEL = (20±2.5), (30±2.5) and (40±2.5) MeV have been obtained. The excitation functions and the angular distributions for Z=6 and Z=8 are presented. It can be observed that as the angular distribution -in this angular range- evolves to more isotropic pattern as TKEL increases when Z of the fragment moves away from Z of projectile. The angular cross correlation coefficient is given for TKEL = (20±2.5 MeV and (40±2.5) MeV as a function of θ and for Z=6 and Z=8, respectively. The high values obtained are explained in the framework of recently developed Partially Overlapping Molecular Levels Model
