✦ Synopsis

the excitation by elect-on impact of the Z3S and 2'S states of helium are measured in the 194'i eV en&Y range. Several shape resonances are observed. An estimate for the 23P cross section is presented. ~OSe-COUpiiIIing ukukltions of Burke et al.'pre&ct the correct structure but overestimate the mqnitude of the measured cross sections.
