Using these equations we calculate the binding energy of the ^3He^4He_2 trimer with the LM2M2 potential by Aziz and Slaman and more recent TTY potential by Tang, Toennies and Yiu.Contribution to Proceedings of "Advanced Study Institute: Symmetries and Spin", PRAHA-SPIN-2001 (Prague, July 15 - July 28, 2001)Atomic and Molecular Clusterstext
