NONLOCALITY IN (HELIUM-HELIUM) INTERATOMIC POTENTIALS

1976
Publisher Summary This chapter highlights the nonlocality in interactomic potentials. Interatomic potentials are usually taken to be purely local. With this assumption, the potential is obtained through the use of Born–Oppenheimer approximation. This usually leads to a long range attractive van der Waals' potential and a short range steep repulsion ...

Helium-3 in Superfluid Helium-4

1974
This paper is not intended to be a review nor is there sufficient time or space to give an adequate introduction to the work which will be described in the many contributed papers at the conference, so I will confine myself to some topics that have interested our group at Ohio State.
