Comparative Study of Potassium Halides Parameters with Many Body and van der Waals Three Body Force Shell Model [VTBFSM]

U. C. Srivastava · Current Journal of Applied Science and Technology · 2011

In present paper authors have used the theoretical model for calculation of value of different model parameters of potassium halides by using the effect of Many body (Puri and Verma, 1977) (Basic model for calculation and aurthor directley used the all calculated value of many bo...

Unified Study of Lattice Dynamic of Potassium Iodide (KI)

U. C. Srivastava & K. S. Upadhyaya · Physical Science International Journal · 2011

A unified description of a series of Phonon properties of potassium iodide (KI) by means of van der Waals three-body force shell model [VTBFSM] is presented. This model includes van der Waals interactions (VWI) and three-body interactions (TBI) in the framework of both ion polari...

Velocity Shear Ion-Cyclotron Higher Harmonics Instability in the Presence of Perpendicular A.C. Electric Field

R. S. Pandey, U. C. Srivastava, A. K. Chaubey & K. M. Singh · Current Journal of Applied Science and Technology · 2011

Velocity shear electrostatic ion cyclotron instability has been studied in the region of auroral ionosphere in the presence of perpendicular A.C. electric field for higher harmonics. The expression for dispersion relation and growth rate has been derived by using the method of ch...
