Abstract
A Feshbach resonance associated with the 1s3s4s 4S state of He- has been observed in the He(1s2s 3S) + e- (εs) partial photodetachment cross section. The residual He(1s2s 3S) atoms were resonantly ionized and the resulting He+ ions were detected in the presence of a small background. A collinear laser-ion beam apparatus was used to attain both high resolution and sensitivity. We measured a resonance energy Er = 2.959 255(7) eV and a width Γ= 0.19(3) meV, in agreement with a recent calculation.
