Using semiclassical S-matrix theory in a simulated electron-hydrogen scattering experiment and converged quantum calculations for the widths of high-lying resonances in we show that resonance formation (or the lifetime of resonances) below the fragmentation threshold E=0 and ionization above threshold have the same energy dependence for . Hence, series of resonances which have been characterized by approximate quantum numbers will disappear towards threshold.
