Binding Energies and Scattering Observables in the ^3He^4He_2 Atomic System

Abstract

The ^3He^4He_2 three-atomic system is studied on the basis of a hard-core version of the Faddeev differential equations. The binding energy of the ^3He^4He_2 trimer, scattering phase shifts, and the scattering length of a ^3He atom off a ^4He dimer are calculated using the LM2M2 and TTY He-He interatomic potentials.Comment: Contribution to Proceedings of the 17th International IUPAP Conference on Few-Body Problems in Physics (Durham, North Carolina, USA, June 5-10, 2003
