Precipitate Dissolution by High Energy Collision Cascades *
The evolution of the microstructure during irradiation is now widely recognized due to: (1) radiation altered kinetic phenomena; (2) collisional processes by energetic cascades. In this paper, we investigate the specific nature of the collisionai interaction between energetic cascades and precipitates. A new Monte Carlo-based computer program, TRIPOS, has been developed for the TRansport of Ion...
متن کاملKinetic electron excitation in atomic collision cascades.
The kinetic excitation of electrons upon bombardment of a solid surface with energetic ions is investigated. Using a metal-insulator-metal junction, hot electrons produced by the projectile impact are detected with excitation energies well below the vacuum level. The results provide information that cannot be accessed by electron emission experiments. The observed tunneling current depends on t...
متن کاملTime-dependent wave-packet treatment of the Si¿He collision
The collisional system Si1He has been studied over a range of mean relative ion kinetic energy going from 10 to 10 eV/amu. In the low-energy range, a time-dependent wave-packet approach is used both in the diabatic and the adiabatic representation using two different propagator techniques. The agreement between the two sets of results assess the accuracy of the present numerical approach. Above...
متن کاملTime-dependent Kinetic Equations with Collision Terms Relatively Bounded with Respect to the Collision Frequency
In this article the existence and uniqueness theory of time dependent kinetic equations is developed for collision terms dominated in the norm by the collision frequency, thus generalizing prior work by Beals and Protopopescu.
متن کاملSimulations of Gamma Cascades and Modelling Atomic Collision Chains
A new method for simulation of nuclear γ cascades by the Monte Carlo technique is described. It makes it possible to generate artificially individual events of the γ-cascade decay of neutron capturing states in heavy nuclei. For the purpose of determination of lifetimes of nuclear levels by the GRID method the previously developed Mean Free Path Approach for modelling atomic collisions and thei...
