A variational calculation is performed for the (/sup 3/He)/sub 4/ system interacting pairwise through the Lennard-Jones He--He potential. Use of an integrodifferential Euler equation is made to determine an optimum wave function, leading to results showing that the existence of this molecule is unlikely. It is confirmed that states of the system with nonzero orbital angular momentum yield lower energies. Also, it appears that the number of /sup 3/He atoms needed to form self-bound molecules must be larger than 5.
