##### 3751 Study of Proton-9,11Li Elastic Scattering at 60~75 MeV/Nucleon

**Authors:**
Arafa A. Alholaisi,

**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.

##### 3741 The Mass Attenuation Coefficients, Effective Atomic Cross Sections, Effective Atomic Numbers and Electron Densities of Some Halides

**Authors:**
Shivalinge Gowda

**Abstract:**

_{2}, CdI

_{2}and HgI

_{2}were determined at photon energies 279.2, 320.07, 514.0, 661.6, 1115.5, 1173.2 and 1332.5 keV in a well-collimated narrow beam good geometry set-up using a high resolution, hyper pure germanium detector. The mass attenuation coefficients and the effective atomic cross sections are found to be in good agreement with the XCOM values. From these mass attenuation coefficients, the effective atomic cross sections s

_{a,}of the compounds were determined. These effective atomic cross section s

_{a}data so obtained are then used to compute the effective atomic numbers Z

_{eff}. For this, the interpolation of total attenuation cross-sections of photons of energy E in elements of atomic number Z was performed by using the logarithmic regression analysis of the data measured by the authors and reported earlier for the above said energies along with XCOM data for standard energies. The best-fit coefficients in the photon energy range of 250 to 350 keV, 350 to 500 keV, 500 to 700 keV, 700 to 1000 keV and 1000 to 1500 keV by a piecewise interpolation method were then used to find the Z

_{eff}of the compounds with respect to the effective atomic cross section s

_{a}from the relation obtained by piece wise interpolation method. Using these Z

_{eff}values, the electron densities N

_{el}of halides were also determined. The present Z

_{eff}and N

_{el}values of halides are found to be in good agreement with the values calculated from XCOM data and other available published values.
