  Study of the role of the electron screening in the $\alpha$ decay is
advanced, aimed at the experimental test in the storage rings. To this end,
systematic calculation of the effect in heavy ions of the nuclei within the Ra
to Po domain of the $\alpha$ emitters is conducted within the adiabatic
approach. The obtained effect is to slow down the decay by an amount within the
percent value. It is of the opposite sign comparing to what is predicted within
the conventional frozen shell model. The reason for this divergence is
demonstrated. Testing this difference experimentally in storage ring facilities
is proposed. It is of great interest for advancing the astrophysical
fundamental research.
