The collision induced by the three Beryllium isotopes, Be, on Zn target were investigated at Ec.m. ≈ 1.4 the Coulomb barrier. Elastic scattering angular distributions were measured for the Be collisions whereas, in the Be case the quasielastic scattering angular distribution was obtained. A strong damping of the quasielastic cross-section was observed in the Be case, especially in the angular r...

optimal conditions are used in nondynamical formalism to diagonalize the pionproton reaction matrix as much as possible. invariance laws are imposed to simplify the relationship between observables and bilinear combination of amplitudes. transverse amplitudes are determined by using measured polarization parameter in xfp elastic scattering at 6.0 gevic
We present a fully microscopic three-cluster nuclear model for light nuclei on the basis of a J-Matrix approach. We apply the Modified J-Matrix method on 6He and 6Be for both scattering and reaction problems, analyse the Modified J-Matrix calculation, and compare the results to experimental data.
Nucleon total reaction and neutron total cross sections to 300 MeV for 12C and 208Pb, and for 65 MeV scattering spanning the mass range, are predicted using coordinate space optical potentials formed by full folding of effective nucleon-nucleon interactions with realistic nuclear ground state densities. Good to excellent agreement is found with existing data.
This talk examines a number of reaction mechanisms for scattering initiated by an exotic projectile. Comparisons are made with recent experimental data, in order to extract information on the peculiarity of the nuclear structure under extreme conditions and to test the accuracy of the available theoretical methods. Predictions for future experiments are also made.
peace and national security protection and ironic solving of international conflicts become the preliminary foundation of the united nations charter and had been considered as the main responsibilities of the security council, after world war ii and the establishment of united nations organization. therefore, the security council enables to analyze every kind of conflicts and challenges which ...
In the present work, the transition matrix elements as well as differential and total scattering cross-sections for positronium formation in Positron-Hydrogen atom collision and hydrogen formation in Positronium-Hydrogen ion collision, through the charge transfer channel by Two-Centre Close-Coupling method up to a first order approximation have been calculated. The charge transfer collision is ...
