Abstract
We present a finite-size scaling approach for the calculations of the critical parameters of the few-body Schrodinger equation. This approac h gives very accurate results for the critical parameters by using a s ystematic 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. [S1050-2947(98)50103- 5].
