Scattering length of the helium atom - helium dimer collision
Elena A. Kolganova, Alexander K. Motovilov, Werner Sandhas
We present our recent results on the scattering length of ^4He-^4He_2 collisions. These investigations are based on the hard-core version of the Faddeev differential equations. As…
Complex Scaling of the Faddeev Equations
E. A. Kolganova, A. K. Motovilov, Y. K. Ho
In this work we compare two different approaches to calculation of the three-body resonances on the basis of Faddeev differential equations. The first one is the complex scaling ap…
Binding Energies and Scattering Observables in the 4Helium3 Atomic System
A. K. Motovilov, W. Sandhas, S. A. Sofianos +1
The 4He3 system is investigated using a hard-core version of the Faddeev differential equations and realistic 4He-4He interactions. We calculate the binding energies of the 4He tri…
Binding Energies and Scattering Observables in the 4^He_3 Atomic System
A. K. Motovilov, W. Sandhas, S. A. Sofianos +1
The ^4He_3 bound states and the scattering of a ^4He atom off a ^4He dimer at ultra-low energies are investigated using a hard-core version of the Faddeev differential equations. V…
Scattering and resonances in the ^4He three-atomic system
E. A. Kolganova, A. K. Motovilov
A mechanism of disappearance and formation of the Efimov levels of the helium ^4He_3 trimer is studied when the force of interatomic interaction is changed. The resonances includin…
Structure of T- and S-matrices in unphysical sheets and resonances in three-body systems
A. K. Motovilov, E. A. Kolganova
Algorithm, based on explicit representations for the analytic continuation of Faddeev components of the three-body T-matrix in unphysical energy sheets, is employed to study mechan…
