The frictional-spectator-interaction (FSI) contributions are computed with two different formalisms for the energy-dependent mean free path. Khan, Ferdous Tripathi, Ram K.Īn optical potential abrasion-ablation collision model is used to calculate hadronic dissociation cross sections for a 14.6 A GeV(exp 28) Si beam fragmenting in aluminum, tin, and lead targets. Optical model calculations of 14.6A GeV silicon fragmentation cross sections A refractory ceramic annular deflector is positioned in each of the enlarged sections, substantially extending the useful life of the valve. Fitted values of the total width to experimental results are used to predict the lifetime of the ablation stage and indicate a decay time on the order of 10 to the -19th power sec.Ī ball valve assembly for controlling the flow of abrasive particulates including an enlarged section at the bore inlet and an enlarged section at the bore outlet. An exponential parameterization of the ablation T-matrix is used and the total width of the intermediate states is taken as a parameter. Townsend, Lawrence W.Īn abrasion-ablation T-matrix formulation is applied to the calculation of double differential- cross sections in projectile fragmentation of 2.1 GeV/nucleon O-16 on Be-9 and 86 MeV/nucleon C-12 on C-12 and Ag-108. At the accretion region has a slope about 2.0° to 3.1° and cross the incision length about 306.62 m to 562.05 m.ĭoubly differential cross sections for galactic heavy-ion fragmentationĬucinotta, Francis A. ASTER GDEM results of image analysis in areas of abrasion has a slope about 1.4° to 3.3° and cross the incision length is approximately 350.52 meters to 506.57 meters.
and experienced accretion with the furthest distance of 31.65 m to 111, 58 m. Western coastal of Banten Province has experienced abrasion with the furthest distance of 125.05 m to 274.73 m. Aster GDEM image is used to determine the slope and the length of cross the incision on exposed area abrasion and accretion. Remote sensing technology is to support the identification and assessment of resources and disasters in coastal areas and oceans, because it has the advantage of covering large areas and the highest of the spatial and temporal resolution. The slope and incision length of affected local cross abrasion and accretion using ASTER GDEM image analysis Results are compared with experimental results and predictions from Glauber theory. Unlike the optical limit of Glauber theory, which cannot be used for very light nuclei, the abrasion formalism is valid for any projectile target combination at any incident kinetic energy for which eikonal scattering theory can be utilized.

Within the context of eikonal scattering theory, a generalized optical model potential approximation to the nucleus-nucleus multiple scattering series is used in an abrasion-ablation collision model to predict abrasion cross sections for relativistic projectile heavy ions. Optical-model abrasion cross sections for high-energy heavy ions There are also large differences in abrasion cross section calculations these differences indicate a crucial role for cluster knockout in the abrasion step. At higher energies, the first and second order solutions are similar. Improved agreement with experimental data for total and absorption cross sections is found when compared with first order (coherent approximation) solutions, especially below several hundred MeV. Second order optical model solutions to the elastic scattering amplitude were used to evaluate total, absorption, and abrasion cross sections for neutron nucleus scattering.
