The purpose of this work is to calculate the ground energy of hydro helium cation (2+) by using the Quantum Monte Carlo method. Using the Diffusion Quantum Monte method, we have to calculate the ground energy of hydro helium Cation (2+).our calculation is based on Slater-Jastrow form. We have developed python code and run this on high-performing computers. A very large number of iterations is required to find the best result. We have used the ‘Hartree unit’ in the calculation of electronic wave functions for atoms and molecules.
