Near-Threshold Photoproduction of eta-mesons on Three-Nucleon Nuclei
N. V. Shevchenko, V. B. Belyaev, S. A. Rakityansky +2
A microscopic few-body description of near-threshold coherent photoproduction of the eta meson on tritium and 3He targets is given. The photoproduction cross-section is calculated…
Low energy scattering and photoproduction of -mesons on deuterons
N. V. Shevchenko, V. B. Belyaev, S. A. Rakityansky +2
Photo-production of -mesons and their collisions with light nuclei are studied within the Alt-Grassberger-Sandhas (AGS) formalism for different parameters of interaction. A…
On the possibility of eta-mesic nucleus formation
S. A. Sofianos, S. A. Rakityansky
A microscopic treatment of eta-nucleus system is presented. Using this, the poles of the amplitude describing elastic scattering of eta-meson off the light nuclei ^2H, ^3H, ^3He, a…
Eta-meson light nucleus scattering and Charge Symmetry Breaking
S. A. Sofianos, S. A. Rakityansky, M. Braun
The η-meson collision with light nuclei, ^2H, ^3H, ^3He, and ^4He, is considered on the basis of a microscopic approach which utilises Faddeev type and Lippmann-Schwinger equations…
The eta-meson light nucleus resonances and quasi-bound states
S. A. Rakityansky, S. A. Sofianos, M. Braun +2
The position and movement of poles of the amplitude for elastic eta-meson scattering off the light nuclei d, t, ^3He, and ^4He are studied. It is found that, within the existing un…
