Clusterization Probability in 14N Nuclei

The main aim of the current work is to examine if 14N 
is candidate to be clusterized nuclei or not. In order to check this 
attendance, we have measured the angular distributions for 14N ion 
beam elastically scattered on 12C target nuclei at different low 
energies; 17.5, 21, and 24.5MeV which are close to the Coulomb 
barrier energy for 14N+12C nuclear system. Study of various transfer 
reactions could provide us with useful information about the 
attendance of nuclei to be in a composite form (core + valence). The 
experimental data were analyzed using two approaches; 
Phenomenological (Optical Potential) and semi-microscopic (Double 
Folding Potential). The agreement between the experimental data and 
the theoretical predictions is fairly good in the whole angular range.
