This work is assigned to study the influence of different interaction potential forms
on the pressure and internal energy of crystalline argon along its isothermal curves at high
temperatures, expanded from melting point temperature up to room temp
erature at
different molar volume values expanded up to its value, corresponded experimental
equilibrium curves with gaseous and liquid phases within the framework of quasi-classical
approximation. The pair-wise inter-atomic forces in conjunction with three-body forces
were taken into consideration. The results of this study regarding the pressure and internal
energy of crystalline Argon were compared with available experimental data. The
comparison clearly indicates that the calculated results coincide well with the experimental
results.
The huge technological advancement and the artist's enthusiasm for the development of original metallic sculpture using non-costly, accessible and natural material that provides sculpting work
continuance and meets his/her innovative instinct as a r
eflection of their faithfulness, patience and technical seriousness.
The sculptors of the twentieth century especially the talented artists as Picasso, calder and cesar chose metal thus translating their amazing skills, creativity and innovation in their works, and expanding
their sculpted achievements in a close and reciprocal relationship between the monument and creativity clearly appears.
In this research, we shed light on a summary of the most three dazzled artists in our age, not to forget that those three artists started with classical realism in their experience in metal works to end with
modern sculpting including abstraction which is manifested in calder and cesar's new works.
Their great works invaded the modern world, thus proving the close relationship between metal and artistic creativity in a statue.
In the present work, a modification of a previously developed electron cascade model
is presented. More than one electronic state is incorporated in the model as well as various
loss processes. Thus, new inelastic process such as photo ionization a
nd electron impact
ionization of the electronic excited state of the argon atom are considered. Moreover, loss
processes which may act to deplete the number of electron such as electron diffusion; three
body recombination and dissociate recombination are taken into account. All these
processes are incorporated into the time-dependent Boltzmann equation which is solved
numerically simultaneously with set of rate equations for both the electron energy
distribution function (EEDF) and the excited state population respectively.
