Cross sections for vibrationally elastic scattering of the system e-C2H6 have been measured with a newly constructed apparatus of the crossed-beam type using the relative flow technique. Absolute elastic differential cross sections for C2H6 were obtained by measuring the ratios to the cross section for He at impact energies of 2, 3, 4, 5, 6, 7.5, 8.5, 10, 15, 20, 40 and 100 eV and angles from 15' to 130'. Integral and momentum transfer cross sections were calculated from the DCS and are compared with other measurements. A short description of the apparatus is given.

The different scattering cross sections and the partial wave scattering cross sections for He-N2 have been calculated by employing the accepted exact Close-Coupling approximation method. It shows that elastic scattering takes place mainly at large scattering and inelastic rotational-excitation chief at small scattering angle at low-energy scattering for He-N2 system. The various rules of the partial wave cross sections in different energy conditions have been found by systemic investigation and calculation.

The differential scattering cross section measurements for selected energies between 2 and 19 eV have been re-analysed to obtain phaseshifts and associated errors which are consistent with the measurements. The phaseshifts obtained from different angular distribution measurements are shown to be consistent with each other within their associated errors and are also consistent with the best available phaseshifts determined by theory. These phaseshifts have also been used to determine total and momentum transfer cross sections which are compared with direct determinations of these quantities. The re-analysis of the differential cross section measurements does not reduce the uncertainty which at present exists in the total cross section at lower energies.

Proton-nucleus reaction cross sections in the energy region from 90 to 300 MeV are computed from elastic-scattering data. The interference of the nuclear scattering amplitude with the calculable Coulomb scattering amplitude determines the magnitude and phase of the nuclear amplitude when the differential elastic-scattering cross section is known. The reaction cross section is then obtained by an application of the optical theorem.

The nuclear optical model has been used in the analysis of elastic scattering for the reaction . This model has six optical parameters; the depth, Coulomb radius and the diffuseness on both the real part and imaginary part potentials. Out of the six, five parameters were chosen and for this case diffuseness parameter on the imaginary part was kept constant. The five parameters were used to calculate the partial wave S-matrix, the differential cross section and the reaction cross section as a ratio to Rutherford cross section. The partial wave scattering data was obtained basing on the quantum mechanical optical code for all the stated Laboratory energies. The angular distribution for the reaction for both reaction cross section to the Rutherford cross-section and differential cross section ranging from centre of mass angles of were also obtained for all the energies, ( and MeV) and whose data and graphs are presented. Key words : Differential cross-section, Reaction cross-section and Partial scattering matrix.

In this paper, the Fuchs potential model and the Close-coupling method are used to calculate the low-energy cross sections for a He-Li2 scattering system. The dependences of total cross section on energies, differential section on angles, and partial wave cross section on quantum number of total angular momentum are discussed . The quantum effect on energy obtained.

Differential cross sections have been measured for elastic scattering of electrons from Kr. Measurements have been performed at impact energies of 5, 7.5, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150 and 200 eV in the angular range from 10 to 125'. Absolute values of the differential cross section have been obtained by means of the relative flow method. Integral and momentum transfer cross sections have been derived from the measured data by extrapolating to 0 and 180 degrees scattering angles. Comparison was made between the present results and those from other experiments and theoretical calculations.
