Bound states with arbitrary angular momenta in nonrelativistic three-body systems

The generalization of the highly accurate exponential variational expansion in the relative coordinates r(32), r(31), and r(21) is presented for the computation of bound states with arbitrary values of the total angular momentum L and space parity pi for three-body nonrelativistic systems with arbitrary particle masses. For all matrix elements explicit analytical formulas are presented which have relatively simple structures and contain L and pi as parameters.
