Atoms and molecules are the fundamental constituents of materials and they are the main key that can open the door to understand the materials’ structures and dynamics. The goal of a computational atomic and molecular physics is to determine numerical solutions of approximate equations. All measurable properties of the atoms and molecules can be obtained by these solutions.In the present work, accurate treatments for both non-relativistic quantum mechanics and relativistic quantum mechanics have been presented.

     In this work,  a DC planner  magnetron  sputtering  system used.  Which  consists  of  a cylindrical  chamber, made from (Borosilicate). It contains two circular  electrodes  made  from  stainless  steel. The  cathode  electrode  is  carried  the  target  material  and  permanent  magnet  while a glass  sample, which  must coat, is  placed  on  the  anode  electrode.  In  this  works,  gold  and  silver used as a target  materials.

          The interacting boson model (IBM) has been used to make a schematic study of (^172-180Hf and ^180-190W) isotopes. For each isotope of Hafnium and Tungsten determined the values of the parameters in the Hamiltonian of IBM-1 and IBM-2, which satisfied the best fit to the experimental data for energy levels. Beside on these values, can extrapolate to isotopes are extrapolated for which no experimental data founded and can make predictions for future experiments.
