摘      要：The computational approach for solving the Faddeev-Merkuriev equations in total orbitalmomentum representation is *** equations describe a systemof three quantumcharged particles and arewidely used in bound state and scattering *** approach is based on the spline collocation method and exploits intensively the tensor product formof discretized operators and preconditioner,which leads to a drastic economy in both computer resources and time.
