The possibility of existence of spherically symmetrical quasi-neutral collective coupling states (CCS) in collisionless plasma is discussed. Correlation phenomena in quasi-neutral systems with hot electron component moving with average velocity close to ion one may occur in greatest degree and guide to the advantage of CCS forming. CCS consists of large numbers of electrons and ions, and represent regions with the potential differing from average (zero) plasma potential. The concept of CCS can be considered as non-linear BGK-waves. This definition is just applied in great degree for equilibrium configurations with non-linear electrostatic field. The simplest spherically symmetrical configuration has been considered without spin and polarisation in the frame of kinetic description for monochromatic on energy electron and ion components and distribution functions on full momentum in forms of simple power functions of different powers for electrons and ions. Asymptotic analytical and full numerical solutions were found for CCS with captured and passing particles turning into final density neutral plasma created chaotically moving electrons and ions in rest.
