Abstract: Continuum hyperspherical harmonics expansion momentum representation transformation (CHHE-MRT) method for three-body problem is briefly introduced, including two-body T matrix and hyperradial function of three-body in bound state or in scattering state. As a check of this method, the binding energies and hyperradial functions in bound states of 3N(3H) and 3α (12C) systems are calculated by using Gauss, exponential and Yukawa potentials, respectively.
