Abstract: Introducing the potential harmonics for the two-body correlation,we modified thecorrelation-function potential-harmonic generalized Laguerre function method (CFPHGLF)previously proposed by us.The new CFPHGLFyields much more accurate eigenenergy forthe ground state 1lS,and slightly better eigenenergies for the excited states 2 lS,3 lS and 4 lSof the helium atom than the original CFPHGLF.

Key words: Hyperspherical coordinates, Potential harmonics, Fast convergence
