Název v původním jazyce

The negative and positive charged two-dimensional three-body systems in addiabatic hyperspherical approach

Popis výsledku v původním jazyce

Binding energies of ground S-1-states for two-dimensional three-body systems (e(-)e(+)e(-), e(-)p(+)e(-), He and Li+), which were received using the hyperspherical adiabatic approach in Born-Oppenheimer approximation, are presented. For description of electron correlation we use K-harmonics, which contain ground angular momentum equal to 0, 2, 4 and 6. We used expansion of potential energy operator in series on multipoles including up to forty terms for description of angular correlations. The values ofbinding energies are four times bigger than in three-dimensional cases with accuracy of about one-two percents. The convergence of energy values according to expansion parameters for channel function is shown. Avoided-crossing regions (R approximate to0.2-5 a.u.) between adiabatic potential U-2(R) and U-3(R) were also found.
