摘要：
A procedure to solve few-body problems is developed which is based on an expansion over a small parameter. The parameter is the ratio of potential energy to kinetic energy for states having not small hyperspherical quantum numbers, K > K (0). Dynamic equations are reduced perturbatively to equations in the finite-dimension subspace with K a (c) 1/2 K (0). Contributions from states with K > K (0) are taken into account in a closed form, i.e., without an expansion over basis functions. Estimates concerning the efficiency of the approach are presented.
