Abstract
Analysis of the differential cross sections for alpha+alpha elastic scattering is performed within the framework of the single and double-folding optical models. For the single folding model an effective alpha-nucleon interaction is used to generate the alpha-alpha real folded potential. For the double folding approach the Paris type of the M3Y effective nucleon-nucleon (NN) interaction is used to generate alpha-alpha real folded potential. Two appropriate density dependence parameterizations, CDM3Y6 and BDM3Y1, have been used for this NN interaction. The obtained potentials in conjunction with phenomenological Woods-Saxon (WS) imaginary potentials are used to investigate the elastic scattering data for several sets of data measured at three different ranges of energy, 6.5-18, 40.8-47.3, and 100-280 MeV. Satisfactory reproduction of the data has been extracted using the obtained potentials.
