In the present paper, the three body ???????? system has been considered using a trial wave function in the variational method. The Schrodinger equation has been written in hyper-spherical coordinate and has been simplified by the proper selection of surface functions. the Schrodinger equation with six-dimensional of freedom reduces to a super geometric equation with one dimension of freedom. By taking a set of basic functions, the energy value of the ground state of the mentioned system has been calculated. The best result of energy for this ion is ?80.38 eV. Relative error percent for this work compared with other works is less than %1.
