Using the CFHH-GLF Method to Solve the H₂ Molecule System Directly: the Selection of Correlation Function and the Analytical Representations of the Correlated Matrix Elements

This paper has given the selation rules of the correlation function when solving Schrodinger equation directly in irregular hyperspherical coordinates using CFHH-GLF method. After chose the correlation function, we have done the reasoning of the equation of the system and given the analytical representation of the correlated matrix elements. We also utilized some characters of Saalschutzian generalizcd hypergeometric functions, Wigner coefficient and Roach Coefficient.
