##### 405 Further Investigation of α+12C and α+16O Elastic Scattering

**Authors:**
Sh. Hamada

**Abstract:**

^{12}C and

^{16}O nuclei. We reanalyzed the experimental elastic scattering angular distributions data for α+

^{12}C and α+

^{16}O nuclear systems at different energies using both optical model and double folding potential of different interaction models such as: CDM3Y1, DDM3Y1, CDM3Y6 and BDM3Y1. Potential created by BDM3Y1 interaction model has the shallowest depth which reflects the necessity to use higher renormalization factor (

**). Both optical model and double folding potential of different interaction models fairly reproduce the experimental data.**

##### 403 Study of Proton-9,11Li Elastic Scattering at 60~75 MeV/Nucleon

**Authors:**
Arafa A. Alholaisi,
Jamal H. Madani,
M. A. Alvi

**Abstract:**

^{9,11}Li elastic scattering differential cross sections in the energy range to MeV have been studied by means of Coulomb modified Glauber scattering formalism. By applying the semi-phenomenological Bhagwat-Gambhir-Patil [BGP] nuclear density for loosely bound neutron rich

^{11}Li nucleus, the estimated matter radius is found to be 3.446

*fm*which is quite large as compared to so known experimental value 3.12

*fm*. The results of microscopic optical model based calculation by applying Bethe-Brueckner–Hartree–Fock formalism (BHF) have also been compared. It should be noted that in most of phenomenological density model used to reproduce the p-

^{11}Li differential elastic scattering cross sections data, the calculated matter radius lies between 2.964 and 3.55

*fm*. The calculated results with phenomenological BGP model density and with nucleon density calculated in the relativistic mean-field (RMF) reproduces p-

^{9}Li and p-

^{11}Li experimental data quite nicely as compared to Gaussian- Gaussian or Gaussian-Oscillator densities at all energies under consideration. In the approach described here, no free/adjustable parameter has been employed to reproduce the elastic scattering data as against the well-known optical model based studies that involve at least four to six adjustable parameters to match the experimental data. Calculated reaction cross sections σ

_{R}for p-

^{11}Li at these energies are quite large as compared to estimated values reported by earlier works though so far no experimental studies have been performed to measure it.
