Magnesium Diboride has attracted the attention of physicists all over the world due to its characteristics band structure and high superconducting(SC) transition temperature 39K. In the present paper the superconducting(SC) state parameters ?, ?* and Tc representing the electron-phonon coupling strength, Coulomb - coupling strength and SC transition temperature of MgB2 have been studied through Harrisons First Principle Pseudopotential [HFPP] technique[1]. The non-local screen form factor w(k, q) of the constituents have been computed through for widely excepted forms of exchange-correlation functions viz. Vashishta Singwi (V-S), Hubbard Sham (H-S), Kleimn -Langreth(K-L) and Shaw (SH) forms. The form factor of MgB2 has been obtained through the well-known Faber-Ziman [2]. The SC state parameters have been completed through the Mc Millan�s Formalism [3]. Reasonable agreement has been obtained with previous and experimental data.
