On inefficiency of repulsive -potentials in multidimensional spaces
I. V. Simenog, B. E. Grinyuk, M. V. Kuzmenko
A complete account of correlations has been shown to make -like repulsive interaction potentials inefficient for any -particle quantum system in the -dimensional space wit…
Energy terms and stability diagrams for the 2D problem of three charged particles
I. V. Simenog, V. V. Mikhnyuk, Y. M. Bidasyuk
Symmetric and antisymmetric terms have been obtained in the framework of the variational approach for two-dimensional (2D) Coulomb systems of symmetric trions XXY. Stability diagra…
Energy Thresholds of Stability of Three-Particle Systems
I. V. Simenog, Yu. M. Bidasyuk, B. E. Grinyuk +1
We have studied the general properties of the energy thresholds of stability for a three-particle system with short-range interaction. A wide region of the interaction constants an…
Can tetraneutron exist from theoretical point of view?
I. V. Simenog, B. E. Grinyuk, Yu. M. Bidasyuk
A theoretical possibility is shown for the bound state of a tetraneutron to exist in the case of the proposed neutron-neutron potentials in the singlet state with two attractive we…
Precise study of the Efimov three-particle spectrum and structure functions within variational approach
B. E. Grinyuk, M. V. Kuzmenko, I. V. Simenog
A precise study within variational approach of the basic properties of the three-particle spectrum and structure functions with Gaussian potential near the critical coupling consta…
Precise Study of Three-Nucleon Systems within a Representation without Explicit Use of the Isospin Formalism
I. V. Simenog, I. S. Dotsenko, B. E. Grinyuk
A representation without explicit use of the isospin formalism is developed for the precise study of few-nucleon systems, and the advantages of the proposed approach are demonstrat…
