Heavy ion nucleus scattering

Summary

The elastic scattering of^6;7Li,^12;13;14C,¹⁴N,¹⁶O and²⁸Si from a number of nuclei between¹²C and²⁰⁸Pb have been studied within the framework of the 3-parameter formalism of the Strong Absorption Model (SAM) of Frahn and Venter. The description to elastic scattering data by the model parameters Λ, Δ and μ is fairly reasonable throughout the whole angular range. The interaction radiusR and surface diffusenessd are determined from the best fit parameters. The mean standard nuclear radius parameterr ₀ extracted from this study is 1.61 fm, in good agreement with literature quoted values, while the diffusenessd is fairly constant. The inelastic scattering of¹⁴C from⁴⁰Ca and⁸⁸Sr and¹⁴N from²⁴Mg and²⁸Si populating the lowest 2⁺ state and also the inelastic scattering of¹⁴C from⁴⁰Ca leading to the lowest 3^- state have been analyzed using the parameters obtained from the elastic scattering with no further adjustment at all. The quadrupole and octupole deformation parameters β₂ and β₃, respectively, are extracted from the analyses. The deformation parameter values are in reasonable agreement with previous studies.
