Description
In this paper we use the results of a 19-state R-matrix calculation to search for resonances in e--He scattering with positions lying below n≤4 states of helium. The resonance positions and widths are calculated. The excitation function of the metastable states (23S+21S) of helium is also calculated and the resonance structures are examined and compared directly with previous measurements. A classification of resonances and designation of 'Wannier ridge' resonances are re-examined in the light of the present 19-state R-matrix calculation. (author)
