[en] The light odd-even nucleus ⁹Be has the lowest neutron threshold (S_n 1.665 MeV) of all stable nuclei. Already the first excited J^π = 1/2⁺ state lies at an excitation energy of several tens of keV above the ⁸Be + n threshold. Parameters of this resonance are of great astrophysical importance. The description of this unbound level is long-standing problem. Due to its closeness to the neutron threshold the resonance has a strongly asymmetric line shape but despite a large number of different experiments there still exist discrepancies between the various deduced resonance parameters. We present high-resolution ⁹Be(e,e') experiments performed at the S-DALINAC and a reanalysis of our old electron scattering data. (orig.)
