A Masters Degree student at King Khalid University (Department of Physics), Mona Said Srheed has presented a study on the structural properties of a mixture of nano atomic aggregates. The student explained that the study aimed at identifying the spectral and structural characteristics of the mixture, and how they relate to the number of atoms as a variable. She also showed that the major and fundamental interest in the study of atomic or molecular aggregates lies in reducing the gap between atomic physics, and the physics of solids. She said, "Through this study, we seek to learn and discover about structure properties - magic numbers - and how it relates to the size of the aggregates "li + xen-lixen". Srheed showed that the research in this work is based on the analogy of an atom interaction or lithium ion (Li) with nano-systems including xzenn atoms(xe) to study compositional properties change with the change of the size of these systems. She added: "This study is based on a model which makes the total energy of the system equal to the total bilateral energies, and which depends on the accuracy of the results of a range of bilateral energies that will be obtained among the best available accounts on the scene." After that it will be the total energy simulation of the system as a function of changing the number of atoms, xzenn to reach fixed structures with a program that depends on the method of Montecarlo. Some of these structures have high stability and symmetry, and the number of atoms xzenn represents magic numbers. For these magic numbers, we must compare energy predecessor and the subsequent, as these data represent spectrums that are similar to experimentalists, thus rendering our results to represent a very important database for the experimentalists.
