Description

The problem of constructing the unitarity S-matrix for the overlapping resonances with the same quantum number, such as |ER1 - ER2| ∼ ΓR2 + ΓR2 is discussed. The interpretation with the help of the Breit-Wigner type formulae of the existing methods of working with overlapping resonances has been studied. 11 refs., 4 figs
