The $n {-} \bar n$ oscillations in neutron fluxes running from Sun to Earth


The process of $n {-} \bar n$ oscillations in the solar cosmic-rays is considered. It is shown that it has high intensity with respect to the analogic processes on the Earth $(I_{c{-}r}/I_{Earth} \propto 10^8)$, because magnetic field strongly suppresses $n {-} \bar n$ oscillations. Energetic dependence of the $\bar n$ and $\bar p$ fluxes at the Earth is also found. Results obtained are argument for searching the $n {-} \bar n$ transitions in experiments with the solar cosmic-rays.
