General integral relations for the description of scattering states using the hyperspherical adiabatic basis
C. Romero-Redondo, E. Garrido, P. Barletta +2
In this work we investigate 1+2 reactions within the framework of the hyperspherical adiabatic expansion method. To this aim two integral relations, derived from the Kohn variation…
The helium trimer with soft-core potentials
A. Kievsky, E. Garrido, C. Romero-Redondo +1
The helium trimer is studied using two- and three-body soft-core potentials. Realistic helium-helium potentials present an extremely strong short-range repulsion and support a sing…
Comparative study of Rare Gas-H triatomic complexes
Paolo Barletta
This paper presents a comparative analysis of complexes made of one Rare Gas (Rg) atom and molecular hydrogen, for all five stable Rg atoms. In particular, the vibrational band ori…
Variational Estimates using a Discrete Variable Representation
M. Lombardi, P. Barletta, A. Kievsky
The advantage of using a Discrete Variable Representation (DVR) is that the Hamiltonian of two interacting particles can be constructed in a very simple form. However the DVR Hamil…
Microscopic study of the He2-SF6 trimers
P. Barletta, A. Fabrocini, A. Kievsky +2
The He2-SF6 trimers, in their different He isotopic combinations, are studied both in the framework of the correlated Jastrow approach and of the Correlated Hyperspherical Harmonic…
Variational description of the Helium trimer using correlated hyperspherycal harmonic basis functions
Paolo Barletta, Alejandro Kievsky
A variational wave function constructed with correlated Hyperspherical Harmonic functions is used to describe the Helium trimer. This system is known to have a deep bound state. In…
