Abstract

We use the following approximation to the potential between two 4He atoms—V(r)=4420 exp(−r2/1.69)−1302 exp(−r2/2.44) (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 4He tetramer. The Schrodinger 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.
