Abstract
Autoionising states of helium have been observed as resonances in the partial cross sections for simultaneous photoionisation and excitation of He, leaving the He+ ion in the n=2, 3, and 4 states. The energies of the observed structures are given together with the widths of the more prominent structures.Keywords
