We present a finite-size scaling approach for the calculations of the critical parameters of the few-body Schrödinger equation. This approach gives very accurate results for the critical parameters by using a systematic expansion in a finite basis set. To illustrate this approach we added detailed calculations for the critical screening length and the critical exponents for the Yukawa potential.
