摘要：
For the zero-range interaction providing a given mass M-2 of the two-body bound state, the mass M-3 of the relativistic three-body system is calculated. We have found that the three-body system exists only when M2 is greater than a critical value M-c (approximate to 1.43 m for bosons and approximate to 1.35 m for fermions, m being the constituent mass). For M-2 = M-c the mass M-3 turns Into zero and for M-2 < M-c there is no solution with real value of M-3.
