QTAIM study of Bonding and Structure of Pure Atomic Clusters,Part III : Nn Clusters (n= 4,6)
DFT and QTAIM computations have been performed on numbers of pure nitrogen cluster speciesi.e. Nn (n = 4, 6) for investigating the structure and bonding. This study is critical since thesemolecules have been nominated as the good synthetic targets of High Energy Materials (HEM).0nthe other hand the decomposition mechanism is closely depends on the bonding pattern. Thislatter concept was searche...
متن کاملAn investigation of neutron direct damages at energies of 0.1-2 MeV on the DNA molecules with atomic structure deduced using Geant4 toolkit
This study proposes a method to estimate RBE of fast neutrons using Monte Carlo simulations. This approach is based on the combination of an atomic resolution DNA geometrical model and Monte Carlo simulations for tracking particles. Atomic positions were extracted from the Protein Data Bank. The GEANT4 code was used for tracking the secondary particles generated by fast neutrons during their in...

متن کاملA COMPARISON BETWEEN THERMAL AND X RADIOGRAPHY FOR STUDYING THE INTERNAL STRUCTURE OF BIOLOGICAL
ABSTRACT Background: With respect to the difference in the interaction of thermal neutron and X rays with matter, using two radiography systems of thermal neutron and X rays will yield highly valuable information for studying the inner structure of biologic samples. Methods: The high sensitivity of thermal neutron to hydrogen, in particular, has led to recognizing this system as a useful tool ...
متن کاملThe HERMES Polarimeter
The HERMES hydrogen target was operated during 1996 and 1997 in the HERA electron ring at DESY to study the spin structure of the proton by deep inelastic lepton proton scattering. An Atomic Beam Source (ABS) injects an atomic hydrogen beam of high intensity and high proton polarization into a storage cell, made of thin aluminum and coated with Driilm. A sampling tube attached on the side of th...
