The ^3He^4He_2$ trimer within the hard-core Faddeev approach

Abstract

We apply a hard-core version of the Faddeev differential equations to the ^3He^4He_2 three-atomic system. Employing the TTY interatomic potential by Tang, Toennies and Yiu we calculate the binding energy of the ^3He^4He_2 trimer and the scattering length of a ^3He atom off a ^4He dimer.
