Fewhyphen;atom3Hendash;4He mixed molecules

摘要

The existence of seven helium molecules, consisting of admixtures of up to five atoms of the two isotopes, is found on the basis of variational calculations using realistic phenomenological heliumndash;helium potentials. The smaller mass of3He has a significant effect on the binding energies, sizes, and particle distributions of these molecules. Also, a generalization of Tjonrsquo;s line to other fewhyphen;body systems is discovered.
