Elastic Scattering of 12C by 12C at Intermediate Energies

Abstract

Using the double folding model (DF), the real part of the central optical potential for the 12C + 12C system is derived. This potential as well as the single-folding cluster model potential (SFC) are used to calculate the total and differential cross sections for 12C elastically scattered on 12C at three laboratory energies, Elab. = 300, 344.5 and 360 MeV. The calculations are carried out with five sets of nucleon-nucleon (NN) interaction of the integrable Gaussian form and two sets of parameters for the nuclear matter density of the harmonic oscillator form. The transparency of the target nucleus is found to increase as the projectile energy increases. Good fits between the present calculations and the experimental data, as well as with previous calculations, are obtained. The simple methods used here for calculating the real part of the optical potential reduce the potential computing time enormously. The suitable choice of NN interaction as well as nuclear matter densities is important.
