We use the following approximation to the potential between two /sup 4/He atoms: V(r) = 4420 exp(-r/sup 2//1.69)-1302 exp(-r/sup 2//2.44) (V in K, r in A). We use the hyperspherical harmonics expansion, with Fabre's optimal subset, to solve for the ground state of the /sup 4/He tetramer. The Schroedinger equation is transformed into an infinite set of second order coupled differential equations (CDE), which we truncate to M equations. We test our program for solving CDE in two appendices. We find that the energy for our model is less than -4.3 K.
