the theoretical calculation of the energies of projectile like fragments (plfs) using the heavy-ion reactions between 76ge and 198pt are reported in this article. the incident beam energy was 635 mev. the calculated values of plfs are compared with the previous experimental results and it is shown that the theoretical calculations of plfs are consistent with the experimental values. the elastic...

The optimized geometry and energy for [K(H2O)n=1-8] clusters have been studied using different basis sets and different methods (HF, MP2(FULL), BLYP and B3LYP). Moreover, two analytical potentials have been developed for potassium in water based on MP2(FULL) and B3LYP computations using the 6311g* for potassium and the aug-cc-pVTZ(H2O) basis set for water. Two molecular dynamics simulations hav...

the n-(2-benzoyl-phenyl) oxalyl derivatives are important models for studying of three-centered intramolecular hydrogen bonding in organic molecules. the quantum theoretical calculations for two crystal structures of n-(2-benzoyl-phenyl) oxalyl (compounds i and ii) were performed by density functional theory (b3lyp method and 6-311+g* basis set). from the optimized structures, geometric paramet...
