NUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS
We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
متن کاملDiffuse Scattering on Graphs
We formulate and analyze difference equations on graphs analogous to time-independentdiffusion equations arising in the study of diffuse scattering in continuous media.Moreover, we show how to construct solutions in the presence of weak scatterersfrom the solution to the homogeneous (background problem) using Born series, pro-viding necessary conditions for convergence and d...
متن کاملDiffuse multiple scattering
A new form of diffraction lines has been identified, similar to Rutherford, Kikuchi and Kossel lines. This paper highlights some of the properties of these lines and shows how they can be used to eliminate the need for sample/source matching in Lonsdale's triple convergent line method in lattice-parameter determination.
متن کاملX-Ray Diffuse Scattering
In this research program, modern x-ray scattering techniques are used to study the structures and phase transitions in novel states of condensed matter. We have two principal experimental facilities. At M.I.T. we have three high-resolution computer controlled x-ray spectrometers using either a conventional or high intensity rotating anode x-ray generator. The angular resolution can be made as f...
