Abstract
It is shown that large number of low energy scattering phenomena can be consistently explained if time‐varying electric multipoles are ascribed to the atomic shell. Scattering experiments allow for estimation of the atomic multipoles and their absolute values and frequencies. It is discovered that atoms of the same chemical properties have multipoles of the same order and only their absolute values and their frequencies are different. From the whole analysis the conclusion is drawn that unperturbed atomic field must be
