Abstract: Based on B spline and two particle angular function, the hyperspherical adiabatic Hamiltonian equation of Helium atom is solved. The hyperspherical potential curves of  1S and 1P  state are presented, the channel functions are analyzed. The result is confirmed with the previous data. The calculation procedure can be used for the high angular momentum problems of three body system.

Key words:  helium, hyperspherical coordinate, B spline
