The electric and magnetic transitions in the [Formula: see text]Mg nucleus are studied based on the calculations of the longitudinal and the transverse electron scattering form factors. The universal sd-shell model Hamiltonian (USDA) is used for calculations. The wave functions of radial single-particle matrix elements are calculated using the Skyrme potential. For the longitudinal form factors, a good agreement is obtained between the calculations and the experimental data. For the transverse form factors, the effective [Formula: see text] factors are made as adjustable parameters in order to describe the experimental data.

In this work, biocompatible gold nanoparticles were synthesized by reducing the chloroauric acid with ascorbic acid as a reducing agent. Colloidal gold nanoparticles were stabilized through nontoxic acacia gum sodium hydroxide .Synthesizing gold nano particle is confirmed by the change in color of chloroauric acid from yellow to ruby red and brown color depending on the stabilizers. The gold nanoparticles were characterized by UV-Visible spectrophotometer. Where the peak of the absorbance of surface plasmon resonance (SPR) was observed between the wave length 526 and 535 nm. The results of zeta potential were found in rang (-19, -40 mv), AFM and TEM images show two different shapes, hexagonal and spherical and the size of gold nanoparticles between 21.5nm and  29nm.

The research was focused on the production, characterization and application of Gold nanoparticles (AuNP s), which can be utilized in biomedical research and environmental cleaning applications.In vitro free radical scavenging activity of synthesized gold nanoparticles (AuNPs) was investigated. There are many studies use chemical method to synthesis gold nanoparticles (AuNPs) using various chemicals do as reducing agents at different conditions. In this study, gold nanoparticles (AuNPs)were synthesized by gel as reducing and stabilizing agent to reduce Au +3 ions form chloroauric acid (HAuCl 4 .3H 2 O) to nano gold .The reactionwere required heating around 60-80 o C.Synthesis of colloidal Au NPs was monitored by UV-Visible spectroscopy. The UV-Visible spectrum showed 524 nm , The characterization of the AuNPs such as their size , shape and stabile was performed by zeta potential , Atomic Force Microscopy (AFM), Transmission Electron Microscopy (TEM) techniques which indicated a size range of 14 to 25 nm. The in vitroantioxidant properties of AuNPs using DPPH assay have been evaluated and these nanoparticles were found to have
